Enhancing the d–Electrocatalytic Activity of MXene Through Defect Engineering

Carbon Energy, EarlyView.
Applications of MXene. ABSTRACT Due to their versatile and tunable surface and bulk chemistry, MXenes have great potential as electrocatalysts for batteries and supercapacitors. When compared with other electrocatalytic processes, in electrocatalytic reactions, MXenes could improve ion diffusion and charge transfer by either providing functional groups

Multiple Active Sites Engineering in Cu/γ‐Al2O3 Catalyst Enables Selective Electrocatalytic CO2 Reduction to Methane at High Rates

Carbon Energy, EarlyView.
A multi‐site heterogeneous electrocatalyst is designed, composed of Cu nanoclusters supported on γ‐Al2O3. Within this system, CO2 activation, H2O dissociation, and *CO protonation are respectively governed by the Cu sites, γ‐Al2O3 sites, and the Cu/γ‐Al2O3 interface sites.

Glycerol carbonate formation from glycerol and dimethyl carbonate using lithium‐based catalysts

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Excess glycerol from biodiesel production can be sustainably converted into value‐added products like glycerol carbonate, for its use in polymers, solvents, and as ecofriendly alternative as green chemical in various chemical industries. This study aims to synthesize a catalyst optimized for the glycerol and dimethyl carbonate (DMC) conversion

A study of Ni‐Co/CeO2 catalyst derived from metal–organic framework for dry reforming of methane

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The efficacy of cobalt‐doped, MOF‐derived catalysts for dry reforming of methane (DRM) was examined. The focus was on the influence of varying nickel and cobalt molar ratios on catalytic performance. Three catalysts with Ni:Co ratios of 1:1, 1:0.5, and 0.5:1, were synthesized and tested with cerium oxide as a constant support. The DRM reaction
