Two main strategies, reducing CO2 emissions and developing sustainable clean energy, are crucial in achieving carbon neutrality. This review highlights the importance of advanced single-atom catalysts (SACs) in converting CO2 into efficient carbon energy and introduces energy conversion technologies and devices that can replace polluting fossil fuels, such as photocatalytic and electrocatalytic water splitting. The review concludes with an overview of the challenges and future applications of SACs in contributing to carbon neutrality.
