To reduce the harmful effects created by the exploitation of conventional sources of energy, there are two prime ways [2]:

1 (i) Find an alternate way to catch the carbon dioxide and release after treatment (generated by fossil fuel consumption) or do not let release carbon dioxide directly into the atmosphere.

2 (ii) To search for other alternative fuels which do not release carbon dioxide gas.

Among the available sources of renewable energy, solar energy and biomass are attaining great attention by researchers worldwide because the combination of solar energy and biomass provides a great platform to pursue a significant research for producing clean and pure renewable fuel.

In solar energy, photons are used to provide heat (low temperature) instead of thermal energy to carry out a chemical reaction and this process is known as photocatalysis (a subcategory of catalysis). There are basically three big advantages of photocatalysis valorization such as purification of air or water, production of clean fuel from renewable sources, and generation of quality chemicals. It is a well-known fact that the less quantity of absolutely freely available solar radiation on the surface is utilizing.

Still, many industries are dependent on the use of conventional fuels due to lack of research in the field of green chemistry in terms of photocatalysis. Plants manufacture their food due to photochemical reactions which is initiated by sunlight and considered as only renewable source for production of food for human beings and animals, conversion of energy into useful ways, and production of various chemicals. This book chapter discusses in brief about types of biomass and their conversion technologies for obtaining valuable chemicals due to photocatalytic valorization.
