Probing Electrocatalyst Design for Product Selectivity in CO2 Reduction
Advanced Science, EarlyView.Selective CO2 electroreduction is controlled by catalyst structure, dynamic surface reconstruction, adsorbate interactions, and reaction microenvironment. This review summarizes Cu‐ and non‐Cu‐based catalysts, single‐atom and molecular systems, degradation pathways, and operando/computational strategies for steering CO2RR toward hydrocarbons ...

Advanced Science, EarlyView.Converting CO2 into advanced carbon materials capable of meeting the rapid lithium storage demands of lithium‐ion batteries creates a mutually beneficial scenario for both energy and environmental sectors. Here, we propose a stepwise CO2 electrolysis approach to transform dilute CO2 into interlayer‐expanded graphite using molten salt electrolyzers ...

Sustainable Mitigation of Greenhouse Gases Emissions
Problemy Ekorozwoju, 2016 The emission and absorption fluxes of CO2 and CH4 in the environment have been characterized. It has been pointed out that the anthropogenic emission of CO2 amounts only to 3% of emissions from the natural sources. It has been also noted that increasing

Advanced Science, EarlyView.With high specific surface area, and adjustable interface, aerogel provides a multi‐functional platform for gas sensing. This review systematically links structural parameters (specific surface area, pore size, heterojunctions) to sensing metrics (sensitivity, selectivity, stability), critically evaluates optimization strategies, and outlines future ...
