Published: November 2019

A Ag-Mn dual co-catalyst deposited on a K2Ti6O13 photocatalyst significantly enhances the photocatalytic CO2 reduction into CO with an extremely high selectivity of 98% by using H2O as an electron donor, owing to the properties of Ag and MnOx species for promoting CO and O2 formation, respectively.

Nano zero-valent iron with a self-forming Co-catalytic surface for enhanced Fenton-like reactions.

Environ Res

School of Chemistry and Chemical Engineering, Hainan University, Haikou, 570228, China. Electronic address:

Fenton reactions, commonly employed in environmental remediation, decompose H₂O₂ using Fe⁺ to generate free radicals. However, the efficiency is often limited by the slow conversion of Fe³⁺ to Fe⁺. In this study, we synthesize zero-valent iron nanoparticles (nZVI) via a green, plant extract-mediated reduction method, resulting in nZVI coated with a reductive polyphenolic layer that enhances Fe³⁺/Fe⁺ cycling.

Heteroatom doping is a promising strategy for optimizing the photocatalytic activity of semiconductors. However, relying solely on single-element doping often poses challenges in modulating the capabilities of semiconductors. Herein, we adopt a strategy of simultaneously modifying ZnInS with the double non-metallic elements nitrogen (N) and oxygen (O) to form (N, O)-ZnInS.

Boosting Propane Dehydrogenation to Propylene via Electron Hole-Hydrogen Coupling on Cobalt Metal Surface.

Angew Chem Int Ed Engl

October 2024

School of Chemistry and Chemical Engineering, Frontiers Science Center for Transformative Molecules, Shanghai Jiao Tong University, Shanghai, 200240, P. R. China.

Nonoxidative dehydrogenation of propane is useful for the high selectivity to propylene but is suffering from the heavy coke deposition on the catalyst surface. Herein, we present a proof-of-concept application of a hole-hydrogen (H) couple on a metallic cobalt surface to decrease the deactivation rate. The coupled H atoms on the Cobalt (Co) surface, partially resulting from propane dehydrogenation, enabled the desorption of propylene to avoid deep hydrogenolysis and coke deposition and realize selective and durable propylene production, while conventional Co metal-based catalysts do not generate propylene.

Radioactive nuclides and highly toxic organophosphates are typical deadly threats. Materials with the function of radioactive substances adsorption and organophosphates degradation provide double protection. Herein, dual-functional polyamide (PA)/polyethyleneimine (PEI)@Zr-MOF fiber composite membranes, fabricated by in-situ solvothermal growth of Zr-MOF on PA/PEI electrospun fiber membranes, are designed for protection against two typical model compounds of iodine and dimethyl 4-nitrophenyl phosphate (DMNP).

One-Pot Conversion of Biomass Saccharides to γ-Valerolactone over a Versatile Tin-Containing Material.

State Key Laboratory of Green Pesticide, Key Laboratory of Green Pesticide and Agricultural Bioengineering of Ministry of Education, State-Local Joint Engineering Lab for Comprehensive Utilization of Biomass, Center for R&D of Fine Chemicals, Guizhou University, Guiyang, 550025, China.

The synthesis of biofuel γ-valerolactone (GVL) from accessible biomass is an attractive and challenging goal. Here, we report an efficient, one-pot, and mild strategy for the efficient production of GVL from various biomass saccharides without using any homogeneous acid as a co-catalyst and molecular hydrogen as a hydrogen donor. A versatile porous tin-containing material (Sn(M)-S) was designed as an individual heterogeneous catalyst.
