Abstract

Respiratory diseases are mainly treated using several symptomatic treatments, supported by oxygen for the patients. During the Coronavirus disease 2019 (COVID-19) pandemic, oxygen concentrators were in high demand, and even after that, many patients lost their lives to this pandemic due to a shortage of oxygen cylinders. This crisis instigated many entrepreneurs to open oxygen plants, which needed a large scale set up. The articles were searched using Google Scholar, Scopus, and Web of Science using appropriate keywords to write this review article. In this review, we have summarized the need for oxygen that can be overcome using artificial photosynthesis. Using solar energy, in the presence of a catalyst, water can be split into hydrogen and various organic product which can lead to oxygen production. The oxygen, so produced, can be stored in oxygen cylinders and supplied to the hospitals for patients in need. The difference between oxygen concentrators and artificial photosynthesis is that in the former, the oxygen present in the atmosphere is concentrated; no new oxygen is produced, whereas in the latter, oxygen is produced from water, which is more useful. The mini review discusses artificial photosynthesis, the process, and the role of nanotechnology to facilitate artificial photosynthesis.
