\u003cp\u003e\u003ci\u003eNanostructured Photocatalysts: From Materials to Applications in Solar Fuels and Environmental Remediation\u003c/i\u003e addresses the different properties of nanomaterials-based heterogeneous photocatalysis. Heterogeneous nanostructured photocatalysis represents an interesting and viable technique to address issues of climate change and global energy supply. Sustainable hydrogen (H2) fuel production from water via semiconductor photocatalysis, driven by solar energy, is regarded as a viable and sustainable solution to address increasing energy and environmental issues. Similarly, photocatalytic reduction of CO2 with water for the production of hydrocarbons could also be a viable solution. Sections cover band gap tuning, high surface area, the short diffusion path of carriers, and more.\u003c/p\u003e\u003cul\u003e\u003cli\u003eIntroduces the utilization of nanostructured materials in heterogeneous photocatalysis for hydrogen fuel production via water splitting\u003c/li\u003e\u003cli\u003eExplains preparation techniques for different nanomaterials and hybrid nanocomposites, enabling improved sunlight absorption efficiency and enhanced charge separation\u003c/li\u003e\u003cli\u003eAssesses the challenges that need to be addressed before this technology can be practically implemented, particularly of identifying cost-effective nanophotocatalysts\u003c/li\u003e\u003c/ul\u003e
