Coupled Photocatalytic Hydrogen Production With Selective Biomass Valorization via Active Sites Construction and Electron Transport Channels Engineering

open access: yesCarbon Energy, EarlyView.
A ternary CdS/1T‐WS2/CNTs heterojunction is in‐situ constructed via hydrothermal method, which is used for photocatalytic biomass reforming (biomass‐derived alcohols, lignin). It exhibits outstanding performance: H2 production rate of 26.17 mmol/g/h for benzyl alcohol (BA), benzaldehyde (BD) generation rate of 8.29 mmol/g/h, 90.06% BD selectivity, 100%

Temperature Distributions in Hollow Cathode Emitters

open access: yes, 2004
Life-limiting processes in hollow cathodes are determined largely by the temperature of the emitter. To support development of cathode life models we have developed a noncontact temperature measurement technique which employs a stepper motor-driven fiber

Unveiling the Potential of Metal and Non‐Metal Modified Porous Carbon for the Electrochemical Reduction of CO2

open access: yesCarbon 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.

Investigating the Electrochemical Double Layer with Quantum‐Chemical Simulations and Implicit Solvation Models

open access: yesChemistry – A European Journal, EarlyView.
ESM‐RISM is applied to model electrochemical interfaces and benchmarked against Poisson–Boltzmann and molecular dynamics results. Density profiles, differential capacitance, and adsorption energetics at the gold–electrolyte interface are analyzed, highlighting the capabilities of this implicit electrolyte framework.
