This book investigates applicability of various emerging strategies to improve important properties and features of metal oxide materials that can be used further to advance their photocatalytic and photoelectrochemical performances. The range of discussed strategies includes introduction of intrinsic and extrinsic deficiencies, fabrication of heterojunction and utilizing of metal nanoparticles in the form of deposited or embedded formations. Each of them is addressed as separate case in order to reach full and comprehensive assessment of their most fundamental principles and basics as...
