Summary: HZSM-5 zeolites modified by phosphoric acid impregnation were used for acrolein production from glycerol. The phosphorus modified nanosheet HZSM-5 showed excellent catalytic performance with high glycerol conversion and acrolein selectivity, as well as improved stability. The addition of phosphorus adjusted the acidity of HZSM-5 zeolite, suppressed coke formation, and prolonged the catalyst lifetime. In addition, diffusion restriction of products played a crucial role in achieving high acrolein selectivity.

Summary: Bio-based glycerol and aldehydes can be effectively utilized through acetalization reaction using novel macroporous sulfonated polystyrene-type resins (MR-SP20-SO3H and MR-SP50-SO3H). The influence of reactants molar ratio, catalyst amount, temperature, and reaction time on the activity and selectivity to acetals has been investigated. Results showed that MR-SP20-SO3H and MR-SP50-SO3H exhibit excellent performance in the acetalization of glycerol derivatives 1,2-propandiol, 1,3-propandiol, 3-methoxy-1,2-propandiol, and monoacetin; these catalytic systems enable recovery and reuse.

Summary: The objective of this work is to evaluate the technical and economic feasibility of producing acrolein and glycerol carbonate from a biodiesel byproduct, glycerol. Simulation and cost estimation were conducted in Aspen HYSYS (R) v8.8. Among the processes analyzed, only glycerol carbonate production was economically viable in the base scenario, while acrolein production was not due to the complex separation system and high dilution of the inlet stream. However, further research on crude glycerol processing and reaction development could make acrolein production feasible as well.

Summary: Biodiesel production has increasingly shifted towards using heterogeneous catalysts derived from biomass, due to their sustainability, economical and eco-friendly nature, ease of recovery, and the potential to eliminate biomass residues. The review discusses various biomass sources as precursors for heterogeneous catalysts, different methods for preparation, their advantages and drawbacks, as well as their performance in biodiesel production. The use of biomass ash or biochar-based catalysts shows promise in biodiesel synthesis, but requires improvements in catalyst load, reaction time, temperature, and methanol-to-oil ratio.

Summary: The surplus production of glycerol as a byproduct of biodiesel has become a pressing issue for the sustainability of the industry. The catalytic transformation of glycerol to value-added chemicals, particularly acrolein, has gained significant attention. Molecular sieves are considered promising catalysts for industrial applications, but a systematic summary on the research carried out for this reaction is lacking. This review provides a comprehensive and critical overview of glycerol dehydration to acrolein over various molecular sieve catalysts, discussing key technical problems and factors influencing the dehydration performance, as well as the reaction mechanism, kinetics, thermodynamics, and future research directions.

Experimental methods confirm the formation of Pt delta+-Ov-Zr3+ structure at the metal-support interface, which serves as the active site for promoting glycerol oxidation. This study provides a valid paradigm for developing heterogeneous catalysts with metal-support synergistic effect for selective oxidation reactions.

Summary: Heterogeneous photocatalysis is an attractive route for converting solar energy into chemical energy. However, the popular photocatalyst titanium dioxide has limitations in initiating photocatalytic processes with visible light. Metal-organic frameworks (MOFs) have emerged as interesting materials for photocatalysis due to their tunability and efficient light absorption, especially when combined with other semiconductors to form heterojunctions. This critical review highlights the progress in the preparation and activity of metal-organic framework-based heterojunction photocatalysts for organic pollutant degradation.

Summary: Bi2WxMo1-xO6 solid solutions and Bi2WO6/g-C3N4 composites were synthesized and characterized, and different modulation techniques were compared for the decomposition of organic pollutants under visible light. The doping strategy showed attractiveness with the highest efficiency achieved by Bi2W0.5Mo0.5O6 in the degradation of methylene blue (conversion of 52.9%, TON = 0.022). Excellent results were obtained with small amounts of H2O2 in the photodegradation of methylene blue (conversion of 97.9%, TON = 0.040) and phenol (conversion of 81.2%, TON = 0.056).

Summary: Bismuth tungstate (Bi2WO6)-based photocatalytic materials are a hot research topic in photo-catalytic energy conversion and environmental remediation due to their advantageous properties. However, the rapid recombination of photogenerated charge carriers in pure semiconductors, including Bi2WO6, limits their activity. The preparation of heterojunctions based on Bi2WO6 has been proven as an efficient and promising strategy to overcome this challenge.
