Carbon Energy, EarlyView.It is demonstrated that waste sawdust, a green, eco‐friendly, and low‐cost biomass byproduct, can be converted into high‐performance hard carbon through the application of a precisely controlled heating rate. This strategy is optimized and validated through first‐principles calculations, achieving precise control over interlayer spacing and pore ...

Carbon Energy, EarlyView.Earth‐abundant metal‐ and non‐metal‐modified porous carbons offer a highly tunable platform for electrochemical CO2 reduction. This review shows how electronic interactions, active‐site coordination, pore architecture, and cooperative catalytic effects jointly govern intermediate stabilization, product selectivity, and device‐relevant CO2RR performance.

Photochemical and Thermal Activation of a Diarylbismuth Azide
Chemistry – A European Journal, EarlyView.We report the synthesis and characterization of a novel diarylbismuth azide and its divergent reactivity upon thermal or photochemical activation. These findings contribute expanding the reactivity landscape of heavy pnictogen compounds and sets the basis for further investigations. ABSTRACT Azides are widely employed in synthesis as convenient nitrene

Experimental methods in chemical engineering: Temperature‐programmed oxidation—TPO
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Temperature‐programmed oxidation (TPO) probes the oxidative capacity and redox properties of solid materials—catalysts, metal oxides, perovskites, and carbonaceous deposits. It identifies coke type, distribution, and reactivity. TPO instruments pass an oxidizing gas (diluted O2$$ {\mathrm{O}}_2 $$, air, or less commonly N2O$$ {\mathrm{N}}_2 ...

Experimental methods in chemical engineering: Temperature‐programmed desorption—TPD
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Temperature‐programmed desorption (TPD) characterizes the surface active sites of functional materials, such as adsorbents (metal hydrides, porous carbons, zeolites, metal–organic frameworks, for example) and catalysts. Solids surfaces are pre‐treated to remove moisture, contaminants, and previously adsorbed species, then a probe molecule (NH3$

ChemSusChem, Volume 18, Issue 6, March 15, 2025.A sustainable alternative to steam cracking, the molten‐salt‐mediated oxidative dehydrogenation (MM‐ODH) of ethane (C2H6) in Li2CO3‐Na2CO3‐K2CO3 (LNK) couples thermal cracking with melt‐mediated CO2 capture to realize commercially competitive C2H4 and CO yields. LNK composition strongly influences MM‐ODH process outcomes.
