Abstract	A photocatalyst is a substance that facilitates chemical reactions when exposed to light, typically ultraviolet (UV) or visible light. Photocatalysts are essential components in various applications, including environmental remediation, water purification, hydrogen production, and solar energy conversion. Metal oxides have proven to be invaluable materials in the realm of economic and environmental applications. Hence, understanding their behavior in photocatalysis is crucial for harnessing their potential in addressing pressing global environmental challenges. The use of metal oxide nanocomposites (MON), from the mixture of two or more oxides or between these oxides and other functional semiconductor materials, have gained increasing attention from researchers and industrial developers as a potential alternative to produce efficient and environmentally friendly photocatalysts for the remediation of water contamination by organic compounds. Thus, this work presents an updated review of the main advances in the use of metal oxide nanocomposites based photocatalysts for decontamination of water polluted by these substances.
