The current surge in atmospheric CO2 poses a critical challenge to global climate stability. To combat this, effective strategies for capturing and utilizing are imperative. Among the available strategies, photochemical reduction emerges as highly promising avenue. However, achieving efficient with superior product selectivity demands well-designed photocatalysts. In this review, we provide an overview of recent advancements designing fabricating metal oxide-based heterojunction nanocatalysts, including novel types such high-entropy oxides MXenes, over past five years, assessing their effectiveness photocatalytic reduction. Emphasis is placed on understanding roles played by oxygen vacancies structural defects enhancing adsorption capacities oxides. Considering role carrier recombination processes efficiency, delve into formation junction potential, well separation charge carriers at interfaces, elucidating impact capabilities metal-oxide heterostructures. Finally, address challenges prospects harnessing nanostructures photoreduction.

Oxygen vacancy (OV) engineering has been widely applied in different types of metal oxide-based photocatalytic reactions. Our study shown that the redistributed OVs resulting from voids CeO2 rods lead to significant differences band structure space. The flat energy within highly crystallized bulk region hinders recombination photogenerated carrier pairs during transfer process. downward curved surface enhances activation absorbents. Therefore, localization through crystal regionalization renders V-CeO2 capable achieving efficient utilization carriers. Practically, rod shows a remarkable turnover number 190.58 μmol g–1 h–1 CO2 photoreduction, which is ∼9.4 times higher than D-CeO2 (20.46 h–1). designed modularization our work expected provide important inspiration and guidance coordinating kinetic behavior carriers OV defect-rich photocatalysts.

One of the strategies to mitigate greenhouse effect is converting CO2 into high-added value products. In this work, a photothermo-catalytic approach, using peculiar Ni-phyllosilicates samples, was applied for conversion solar fuels. particular, were modified with introduction Ce ions in their structure and successively they covered CeO2 semiconductor. The structural, morphological, textural, optical reducibility properties as well interaction investigated. Ni/Ce-phyllosilicate achieved 87% after 5 hours test simulated irradiation at 120°C, producing 15.8 μmol/gcat∙h CO 5.6 CH4. same sample tested an integrated approach where evolved by catalytic oxidation toluene then converted CH4, obtaining 50% 8.8 μmolCO/gcat∙h 3.3 μmolCH4/gcat∙h. presence Ni phyllosilicates guaranteed good stability whereas deposition allowed exploit improved thermal (redox) cerium oxide favoured adsorption on its basic sites oxygen vacancies. Furthermore, high surface area as-synthetized permitted efficiently expose surface-active radiation. here investigated catalysts showed versatile ideal hybrid approaches photothermo-catalysis, allowing propose new solutions valorization.
