Efficient Solar‐Driven Interfacial Steam‐Electricity Co‐Generation by Modular Design of CAU‐23/Graphene Hybrid Evaporator

open access: yesCarbon Energy, EarlyView.
A dual‐functional evaporator based on CAU‐23/graphene hybrid is acquired through a modular design strategy. Owing to superior broadband light absorption, optimal wettability, and porous architecture that synergistically integrates nanoconfined ionic channels with photothermal conversion, it exhibits a high evaporation rate of 2.71 kg m−2 h−1 with the ...

Influence of Contact Pressure on Performance and Crossover in Zero‐Gap Alkaline Water Electrolysis

open access: yesChemie Ingenieur Technik, EarlyView.
Cell performance and product gas quality in zero‐gap alkaline water electrolysis are influenced by the mechanical contact pressure in the electrode area. With a newly developed contact‐pressure cell, it was found that the influence of contact pressure can vary drastically, depending on the cell configuration, electrode type, and diaphragm.

Experimental methods in chemical engineering: Temperature‐programmed oxidation—TPO

open access: yesThe 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 ...
