Catalysts (ISSN: 2073-4344) has launched the Section “Photocatalysis”. This Section is dedicated to publishing original, novel, and high-impact contributions related to the cross-disciplinary fields of photochemistry, photoelectrochemistry, and catalysis, and it will attract the interest of chemists, physicists, biochemists, surface and materials scientists, and engineers. Photocatalysts are of great importance since they can be utilized in a large array of research fields, including solar energy conversion, photosensible sensors, wastewater and air treatment, organic as well as inorganic synthesis, and surface science and storage devices.

As they are presented in an open access format, you have free and unlimited access to the full text of all the articles published in our journal. We welcome you to read our most highly cited papers published in 2022 and 2023, as follows:
