Summary: Due to the depletion of fossil fuels and their-related environmental issues, the search for sustainable, clean, and renewable energy sources has become urgent. One of the most promising clean energies is hydrogen. Among the various methods of hydrogen production, photocatalysis using carbon nitride has gained significant attention due to its low cost, abundance, appropriate bandgap, and high performance. This review discusses the carbon nitride-based photocatalytic hydrogen production system, including the catalytic mechanism and strategies for improving performance. It also outlines current trends in screening and designing superior photocatalytic hydrogen production systems.

Summary: By constructing 1D strip-like carbon nitride from carbon-doping, this study addresses the issues of high carrier recombination rate and low charge transfer efficiency, improving the hydrogen evolution rate significantly. The effective pi delocalization and porous structure of the carbon-doped 1D carbon nitride play a key role in accelerating charges and mass transfer, leading to a much higher hydrogen evolution rate compared to polymeric carbon nitride under visible light irradiation.

Summary: The ideal photocatalyst for photocatalytic water splitting should have strong light absorption, fast charge separation/transfer ability, and abundant active sites. Heteroatom doping offers a promising approach for optimizing photocatalytic activity. In this study, boron (B) and sulfur (S) dopants were simultaneously introduced into graphitic carbon nitride (g-C3N4) nanotubes using a supramolecular self-assembly strategy. The developed B and S co-doped g-C3N4 nanotubes exhibited outstanding photocatalytic performance, achieving a conversion rate of H2O to H-2 of 9.321 mmol g(-1)h(-1), with an external quantum efficiency of 5.3% under irradiation at λ = 420 nm. The introduction of B dopants facilitated H2O adsorption and interatomic electron transfer, while S dopants promoted the oxidation ability of g-C3N4 and inhibited recombination. Furthermore, the simultaneous introduction of B and S optimized the electronic and energy level structures of g-C3N4 for efficient charge transfer, ultimately maximizing photocatalytic performance.

Summary: Acetamide- or formamide-assisted in situ strategy has been developed to synthesize self-doped g-C3N4 (AHCN(x)) or nitrogen vacancy-modified g-C3N4 (FHCNx). The preorganization step of acetamide (or formamide) with urea via freeze drying-hydrothermal treatment allows precise regulation of the chemical structures and doping levels in AHCN(x) and the vacancy concentration in FHCNx. AHCN(x) and FHCNx demonstrate significantly enhanced visible-light photocatalytic performance for the oxidation of emerging organic pollutants and the reduction of proton to H-2 compared to unmodified g-C3N4, due to their different charge separation and transfer mechanisms and improved visible-light harvesting capacity and localized charge distributions.

Summary: The photoexcited charge separation efficiency is usually considered as the key factor for enhancing the photocatalytic activity of photocatalysts. However, the role of the interfacial affinity between photocatalysts and substrates is rarely studied systematically. In this study, nitrogen vacancy-modified polymeric carbon nitride porous nanotubes (PCNpts) were synthesized and showed significant improvements in surface area, wettability, photoabsorption, charge separation capability, and photocatalytic activity in water splitting. Interestingly, the photoactivity of PCNpts showed substrate-dependent variation in contaminant degradation compared with bulk PCN. It was found that the interfacial affinity between PCNpts/PCN and contaminants/H2O, rather than the photoabsorption and charge separation capability, dominated their photoactivity.

Summary: Ethylbenzene (EB) oxidation to oxygenated products is studied using carbon nanotubes (CNTs) and CNTs with confined cobalt nanoparticles (Co@C/CNTs) as catalysts. Co@C/CNTs show enhanced interfacial charge transfer and improved overall activity by speeding up elementary steps and reducing energy barriers. The rate-determining step is confirmed to be the homolytic cleavage of peroxide. The predicted results and experimental data for the ratio of acetophenone (AcPO) to 1-phenylethyl alcohol (PEA) are in close agreement, indicating the dominant role of AcPO synthesis in the reaction route.

Summary: A nitrogen-doped carbon black electrocatalyst with good performance for the electrochemical CO2 reduction reaction (ECRR) was prepared using carbon black and formamide as raw materials. The nitrogen content was found to improve the CO selectivity, while excessive oxygen content inhibited the ECRR activity. Density functional theory calculations supported that carbon materials with high nitrogen doping amount and low oxygen content would enhance the ECRR performance.

Summary: The objective of this work is to investigate the adsorption separation of liquid-phase xylene isomers using ultramicroporous carbon spheres. The synthesized glucose-based adsorbent (UMC-xyl) exhibits excellent performance in p-xylene/m-xylene separation, surpassing commercial adsorbents including the industrial benchmark KBaX. The micropore diffusion model provides a better fit to the adsorption kinetics of UMC-xyl and the narrow ultramicropore size in UMC-xyl facilitates the separation of xylene isomers.

Summary: Converting CO2 into valuable chemicals and fuels through clean and renewable energy electricity is crucial for sustainable development. This study prepared carbon coated nickel catalysts (Ni@NCT) using solvothermal and high-temperature pyrolysis methods, and obtained Ni@NC-X catalysts by pickling with different acids. The results showed that Ni@NC-Cl treated with hydrochloric acid exhibited the best activity and selectivity for electrochemical CO2 reduction reaction (ECRR), with a considerable CO yield of 472.9μmol h-1 cm-2 at -1.16 V. Controlled experiments revealed a synergistic effect between Ni and N. Theoretical calculations supported the correlation between activity and selectivity of ECRR on different acid-washed catalysts.

Summary: The 5-hydroxymethylfurfural oxidation reaction is a promising method for producing valuable chemical products from biomass. Selective oxidation of the aldehyde group in 5-hydroxymethylfurfural resulted in the production of 5-hydroxymethyl-2-furancarboxylic acid on Au/anatase and Au/rutile catalysts under photoexcited and dark states. Visible light irradiation improved the reactivity of the oxidation reaction, with the effect being more pronounced at lower reaction temperatures. The main active species were O-1(2) and trace amounts of O2(-) under dark conditions, while under visible light irradiation, the main active species were O2(-), O-1(2), and h(+) for both Au/rutile and Au/anatase catalysts.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
