Summary: The study of hydrogen energy is gaining attention for its effectiveness in achieving net zero and environmental sustainability. Bioethanol is a carbon-neutral fuel for hydrogen production and has potential as a sustainable energy source. This research assesses different routes for ethanol reforming and evaluates the impact of catalyst physicochemistry and experimental parameters on hydrogen production. The findings show that non-noble metals like Co and Ni are more reactive than noble metals in ethanol steam reforming, while the sequence of hydrogen selectivity differs in autothermal reforming of ethanol. The review highlights the importance of sustainable hydrogen production and decarbonization in reaching the net zero target.

Summary: Autothermal Chemical Looping Reforming (a-CLR) is a promising technology for CO2 capture and energy minimization in syngas production, utilizing a dual-fluidized bed process. A 1-D multiscale model was developed to study the feasibility, showing realistic results with precautions on oxygen carrier and oxidant ratios. Co-feeding CO2 with CH4 and H2O allows for adjusting syngas composition, but increases the risk of coke formation.

Summary: This study demonstrates a facile aerosol-based method to prepare hybrid nanostructures for catalyzing steam-promoted CO2 reforming with methane. The resulting NiPdOx-CeO2 nanoparticles deposited on SiO2 nanoparticle clusters exhibit superior catalytic performance at low temperatures, with high turnover frequency, tunable H2/CO ratio, and long-term operation stability. Incorporating SiO2 nanoparticle clusters as support material helps to enhance the dispersion of active metals and suppress metal sintering.

Summary: Blue hydrogen production by steam methane reforming (SMR) with carbon capture is the most commercially viable method, and sorption-enhanced steam methane reforming (SESMR) can further decrease the cost of H2 production. Introducing additional metal elements to improve the performance and prevent catalyst deactivation has been an effective solution. This review summarizes recent developments and highlights the potential of bi/polymetallic catalysts for SMR.

Summary: Dry reforming of methane (DRM) is a promising process for producing synthetic gas, and the design of an effective catalyst is crucial. In this study, nickel catalysts supported by calcium hydroxyapatite (HAP) and HAP-doped magnesium (Mg_HAP) were synthesized and evaluated in the DRM reaction. The Ni/HAP and Ni/Mg_HAP catalysts showed outstanding performance due to the tunable acidity-basicity of the supports, strong metal-support interaction, and good thermal stability of nickel nanoparticles. The main products were H2 and CO, with stable selectivity around 85%, while H2O and solid carbon were byproducts with 5-10% selectivity.

Summary: The parallel electrodes gliding plasma (PEGP) is a novel approach for the dry reformation of methane, providing high conversion rates and energy efficiencies. Compared to traditional glide plasma, PEGP demonstrates superior performance in molecular dissociation. By dissipating the energy in the layers of fresh reactants gas instead of overheating or dissociating the products, higher performance is achieved.

Summary: A bulk gamma-Al2O3 catalyst demonstrated high selectivity for propane dehydrogenation after pretreatment and co-feeding with H2S. It was found that H2S irreversibly modified the active sites of the catalyst, leading to increased activity and selectivity towards propylene. Additionally, the formation of sulfurous coke and strong adsorption of reaction products resulted in a less active catalyst.

Summary: Initiated by incipient wetness impregnation, dispersed tin atoms were deposited on gamma-Al2O3. Various characterization techniques were used to analyze the morphology and structure of the catalysts, revealing isolated and well-dispersed Sn oxide sites at relatively high coverages. The study suggests that active catalytic sites during propane dehydrogenation involve Al2O3 rather than bulk sulfide and Sn atoms dispersed over alumina.

Summary: Anthropogenically derived phosphate-bearing crystalline materials play a crucial role in nutrient recycling to the environment, and their reactivity is influenced by the relative humidity at the soil surface. This study investigates the water uptake behavior of two anthropogenically derived phosphates, hydroxyapatite (HAP) and struvite, and finds that their water adsorption properties are influenced by the surface structure and relative humidity. HAP demonstrates a stable surface structure and follows traditional adsorption models, while struvite exhibits intrinsic instability leading to non-convergent adsorption behavior.

Summary: Ammonium carbonates, including ammonium bicarbonate, ammonium carbonate hydrate, and ammonium carbamate, were once extensively used as fertilizer materials but gradually replaced by urea fertilizers. With the emergence of sustainable agriculture, there is a need to recover and reuse nutrients using conventional feedstocks and biogenic waste streams. Anaerobic digestion liquid presents a convenient source to produce solid fertilizers containing nitrogen and carbon. This review discusses the feedstocks, methods to concentrate and crystallize solid ammonium carbonates, technologies to stabilize them in the environment, and their agricultural efficiency as nitrogen and carbon sources.
