Summary: This review focuses on various catalysts, such as heterogeneous catalysts, nanocatalysts, biocatalysts, bifunctional catalysts, metal-organic frameworks (MOF), and covalent organic frameworks (COF), for biodiesel production. The use of homogeneous catalysts in commercial biodiesel production has limitations, such as toxicity, corrosion, soap formation, and non-reusability. As alternatives, heterogeneous acid and base catalysts have been introduced, which are less sensitive to moisture and FFAs, easily separated and recovered, and reusable. Novel catalysts, including waste biomass-derived mesoporous heterogeneous catalysts, chemically synthesized heterogeneous catalysts, metal ion-doped heterogeneous catalysts, bifunctional acid-base catalysts, and carbonaceous char-supported hetero catalysts, nanocatalysts, MOF and COF catalysts, show potential for sustainable and cost-effective biodiesel production. This review provides insights into catalyst advancements, preparation and operations, catalyst types and suitability, efficiency, life cycle assessment, challenges, and prospects for biodiesel production.

Summary: The surface and interface coordination structures of heterogeneous metal catalysts play a crucial role in their catalytic performance. However, the complex structures make it challenging to identify the molecular level structure of active sites and control their performance precisely. Atomically dispersed metal catalysts (ADMCs) and ligand-protected atomically precise metal clusters (APMCs) have emerged as important model heterogeneous catalysts, bridging the gap between homogeneous and heterogeneous catalysis. This review explores how the surface and interface coordination chemistry of these model catalysts determine catalytic performance from various perspectives.

Summary: The development and application of trimetallic nanoparticles are rapidly accelerating in the field of catalysis, presenting exciting opportunities. Current methods for design, synthesis, analysis, and application of trimetallic nanoparticles have been explored, but challenges in controlling elemental segregation and identifying influential characteristics remain. The multielement composition of trimetallic nanoparticles exhibits beneficial synergy in oxidation, dehydrogenation, and hydrogenation reactions, but further work is needed to maximize productivity. Computational support is crucial for experimental endeavors, and the marriage of simulation and experiment is necessary to advance this field. Clear challenges remain in identifying, making, and applying trimetallic catalysts efficiently, but the outlook is strong.

Summary: Single-atom catalysts (SACs), single-atom alloys (SAAs), and ensemble catalysts are heterogeneous atomic catalysts with intentionally controlled surface metal atomic structures. These catalysts have received significant attention for their ability to fully utilize precious metals and induce unique surface reactions. However, durability and stability are crucial factors that need to be considered for practical applications. The properties of the support material and the susceptibility to impurities can significantly affect the performance of these catalysts. High durability heterogeneous atomic catalysts have great potential for sustainable chemical production.

Summary: In this study, induction heating was used to enhance the catalytic performance of Suzuki-Miyaura cross-coupling reactions by employing conductive superparamagnetic microspheres loaded with Pd nanoparticles as heterogeneous catalysts. Compared to conventional joule heating, the reactions using induction heating exhibited better catalytic performance with higher conversion and yield. The improvement is mainly attributed to the localized heating effect and high efficiency of heat transfer.

Summary: Due to food shortages and increasing fuel prices, scientists are exploring alternative non-edible feedstocks, such as jojoba and Schizochytrium sp. microalgae, for sustainable biodiesel production. The use of low-cost nanocatalysts, like CaO, instead of homogeneous catalysts can reduce the cost and eliminate certain steps in the biodiesel production process. The findings highlight the potential of nano-catalysts in achieving high biodiesel yields with their unique features of high surface area, reusability, reactivity, and environmental friendliness.

Summary: Subtilisin integrated artificial plant-cell walls (APCWs) were fabricated by self-assembly with cellulose or nanocellulose as the main component. The resulting APCW catalysts showed excellent catalytic performance for the asymmetric synthesis of (S)-amides. The APCW catalysts could be recycled for multiple cycles without loss of enantioselectivity. The assembled APCW catalysts also cooperated with homogeneous organoruthenium complexes to achieve co-catalytic dynamic kinetic resolution (DKR) of chiral primary amines.

Summary: To increase chemical reaction rates, general solutions include increasing the concentration/temperature and introducing catalysts. In this study, the rate constant of an electrophilic metal coordination reaction is accelerated 23-fold on the surface of layered aluminosilicate (LAS), where the reaction substrate (ligand molecule) induces dielectric polarization owing to the polar and anionic surface. This unique method to accelerate the chemical reaction is expected to expand the range of utilization of LASs, which are chemically inert, abundant, and environmentally friendly. The concept is also applicable to other metal oxides which have polar surfaces, which will be useful for various chemical reactions in the future.

Summary: We propose utilizing laser-assisted carbonization of surface-grown UiO-66 to diversify the upcycling of waste PET into materials with enhanced photothermal properties. A solvo-thermal procedure was used to form a homogeneous UiO-66 layer on recycled PET sheets. Treatment with a 405 nm laser system enabled the formation of a carbonaceous layer with improved electrical conductivity and photothermal properties due to the presence of zirconium carbide and graphene. This approach presents new possibilities for the application of upcycled PET-based materials.

Summary: Hierarchically porous bimetallic zeolitic imidazolate framework (ZIF) particles (etched Zn33Co67-ZIF) were designed and prepared through an ethylene glycol-assisted aqueous etching method, which effectively increased their pore size and surface area. After thermal treatment, the etched Zn33Co67-ZIF particles transformed into cobalt and nitrogen co-doped hierarchically porous carbon (etched Zn33Co67-C), which exhibited increased mesoporosity and specific capacitance compared to the unetched one. The presented ethylene glycol-assisted aqueous etching process provides a facile template-free strategy for improving the energy storage performance of MOFs and their corresponding porous carbons.

Summary: In this study, a hybrid material of pyrazine-based pi-conjugated organic molecule, hexaazatrinaphthalene (HATN), and MXene was reported. The combination of MXene as a conductive substrate and HATN as an electroactive material resulted in a unique 3D structure with increased ion transport channels, leading to enhanced charge transfer and ion diffusion rates. The obtained HATN/MXene composite exhibited a high desalination capacity of 57.5 mg g(-1), a fast desalination rate of 13.2 mg g(-1) min(-1), and good long-term stability. This work provides valuable insights for the design and application of organic molecules in the field of capacitive deionization.

Summary: High-quality emission centers in two-dimensional materials, such as carbon-enriched hexagonal boron nitride (hBN:C) layers, are promising for future photonic and optoelectronic applications. By placing hBN:C layers on Ag triangle nanoparticles (NPs), the decay time of atom-like color-center (CC) defects is accelerated to 46 ps from their bulk value of 350 ps, due to efficient excitation of plasmon modes. Simulations suggest higher Purcell values, and analysis reveals the influence of NP thickness on the Purcell factor of CCs. The ultrafast operation of CCs in hBN:C layers enables their use in demanding applications like single-photon emitters and quantum devices.
