Abstract

Photocatalytic CO2 reduction is the use of solar energy to catalyze the conversion of CO2 into a fuel with added value, and it is an effective way to reuse CO2 to achieve carbon neutrality. In this study, NiAl–layered double hydroxides (LDH)/Bi2Sn2O7–Ov/CuO–Ov composites with double oxygen vacancies are successfully prepared, and the effects of different component contents are investigated. The main products of the best sample NiAl–LDH/BSOv-40/CuOv-20 are carbon monoxide, methane, and ethane with yields of 29.95, 18.46, and 32.13 μmol g−1 h−1, respectively, and a selectivity of 68.15% for the C2H6 product. The evolutionary pathway and photocatalytic mechanism of CO2 are investigated by in situ Fourier transform infrared spectroscopy and theoretical calculations. In this work, the scope of application of oxygen vacancy catalysts for C2 production in the field of photocatalysis is broadened.

层状双氢氧化物/ Bi2Sn2O7-Ov / CuO-Ov双氧空位光催化剂光催化还原CO2高选择性转化为C2H6
光催化CO2还原是利用太阳能催化CO2转化为具有附加值的燃料,是CO2再利用实现碳中和的有效途径。本研究成功制备了具有双氧空位的nial层状双氢氧化物(LDH)/ Bi2Sn2O7-Ov / CuO-Ov复合材料,并考察了不同组分含量对复合材料的影响。最佳样品NiAl-LDH /BSOv-40/CuOv-20的主要产物为一氧化碳、甲烷和乙烷,产率分别为29.95、18.46和32.13 μmol g−1 h−1,C2H6的选择性为68.15%。利用原位傅里叶变换红外光谱和理论计算研究了CO2的演化途径和光催化机理。本工作拓宽了氧空位催化剂在光催化领域的应用范围。

期刊介绍: Solar RRL, formerly known as Rapid Research Letters, has evolved to embrace a broader and more encompassing format. We publish Research Articles and Reviews covering all facets of solar energy conversion. This includes, but is not limited to, photovoltaics and solar cells (both established and emerging systems), as well as the development, characterization, and optimization of materials and devices. Additionally, we cover topics such as photovoltaic modules and systems, their installation and deployment, photocatalysis, solar fuels, photothermal and photoelectrochemical solar energy conversion, energy distribution, grid issues, and other relevant aspects. Join us in exploring the latest advancements in solar energy conversion research.
