Special Issue Information

Dear Colleagues,

The gradual increase in CO2 emissions is an urgent issue, threatening the sustainable development of human civilization. Recently, CO2 reduction reaction (CO2RR) to fuels and feedstocks has arisen as a promising and eco-friendly strategy to close the anthropogenic carbon cycle and store renewable energy.

The generation of reduced valuable carbon chemicals such as carbon monoxide, methane, methanol, formic acid (C+), ethylene, and ethanol (C2+) is highly desirable for both the decrease in CO2 itself and the potential industrial applications of reactants. Recent developments in catalysts have boosted catalytic activities and product selectivities, bringing the CO2RR to practically promising levels. However, determining how to tackle the three challenges of the activity, selectivity, and stability of various catalysts through both theoretical design and experimental synthesis is still challenging.

Therefore, Catalysts is publishing a Special Issue entitled “High-Performance Catalysts Used for CO2 Reduction Reaction, from Principles to Applications”. We are soliciting original high-quality articles and reviews on specific topics that include but are not limited to the following:

  1. Mechanism of CO2RR on various catalysts, from monocarbon to multicarbon oxygenate and hydrocarbon products;
  2. State-of-the-art catalysts for CO2RR;
  3. New descriptors developed with DFT or AIMD methods for CO2RR;
  4. New characterization methods developed during online determination of intermediates during CO2RR.

CO2 reduction to CO as raw material for conversion to chemicals and gasoline fuels via the reverse water–gas shift (RWGS) reaction is generally acknowledged to be a promising strategy that makes the CO2 utilization process more economical and efficient. Cu-based catalysts are low-cost and have high catalytic performance but have insufficient stability due to hardening at high temperatures. In this work, a series of Cu-based catalysts supported by MoOx were synthesized for noble metal-free RWGS reactions, and the effects of MoOx support on catalyst performance were investigated. The results show that the introduction of MoOx can effectively improve the catalytic performance of RWGS reactions. The obtained Cu/MoOx (1:1) catalyst displays excellent activity with 35.85% CO2 conversion and 99% selectivity for CO at 400 °C. A combination of XRD, XPS, and HRTEM characterization results demonstrate that MoOx support enhances the metal-oxide interactions with Cu through electronic modification and geometric coverage, thus obtaining highly dispersed copper and more Cu-MoOx interfaces as well as more corresponding oxygen vacancies.
