Photocatalytic CO2 reduction plays an important role in solar energy storage and carbon balance. GaN as an III‐V semiconductor material has received extensive attention in the field of photocatalysis. In this study, the porous indium‐doped GaN (In/GaN) micro‐rods are synthesized successfully by a facile hydrothermal method and subsequent controlled atmosphere heat treatment. Photocatalytic CO2 reduction performance of In/GaN is higher than that of pure GaN due to the In doping improves the light absorption efficiency. The primary products are CO and CH4. Among the samples, 3%‐In/GaN exhibits the highest catalytic activity as well as stability and reusability. The yield rates of CO and CH4 can be reached 50.2 and 14.6 µmol · g−1 · h−1, respectively. Furthermore, density functional theory (DFT) calculations reveal that the bandgap is narrowed and the adsorption energy of CO2 molecules is improved by In doping. Moreover, the N‐vacancy detected by electron paramagnetic resonance (EPR) increases with the In doping, resulting in an increase in the number of unpaired electrons, which is conducive to carrier transport. This work provides a new study In/GaN prepared by simple method for the light‐driven photocatalytic conversion of CO2 to high‐value‐added products.

“…Harnessing solar energy to isolate hydrogen from water and utilizing it alongside CO 2 to produce organic fuels presents an ideal approach for addressing global energy concerns and combating the adverse effects of CO 2 emissions, which are primarily responsible for global warming. [1][2][3][4][5][6][7] Despite extensive research, conventional biological and electrocatalytic systems have failed to achieve the required efficiency levels, primarily due to inherent stability issues and electrode corrosion vulnerability. However, photo-hydrogen extraction from water offers a sustainable method to harness solar energy efficiently, with minimal environmental repercussions.…”

“…Human activities, such as the extensive use of fossil fuels (coal, gas, oil, wood, and other organic materials) and other greenhouse 10.11113/mjfas.v19n6.3224 gases, also contribute to the increase in CO2 levels. CO2 gas, which is present in more than half of the Earth's atmosphere causes food shortages, forest fires, declining animal populations, and environmental damage [2][3][4][5][6][7]. Even more devastating are the natural disasters brought on by global warming, including the rise in sea level, heat waves, storms and floods, and other catastrophes [3,4,8].…”

Carbon dioxide (CO2) is a major greenhouse gas present in over half of the Earth's atmosphere. Elevated CO2 emissions in the atmosphere have become a global warming issue due to the excessive use of fossil fuels by human activities. Converting CO2 into a useful compound is crucial since CO2 exists in the environment and must be reduced. The use of semiconductor materials in photocatalysis is the best solution to degrade and potentially convert CO2 into a useful energy source. Recently, research on graphitic carbon nitride (g-C3N4) has developed interest due to its phenomenal properties, such as effective charge separation and charge carrier lifetime, electron-hole recombination, and high surface area. CQDs/g-C3N4 has recently emerged as a novel technology due to its excellent physical and chemical properties, especially in the reduction of CO2. Thus, this review outlines the recent modification of graphitic carbon nitride (g-C3N4) by carbon quantum dots (CQDs), which include the synthesis of CQDs/g-C3N4 for CO2 reduction. Lastly, the review discusses physicochemical properties-photocatalytic activity relationship of CQDs/g-C3N4 in the photocatalytic reduction of CO2. This review provides a wide range of perspectives and a guideline for designing the more effective CQDs/ g-C3N4 for photocatalytic reduction of CO2.
