Significant efforts have been dedicated to hydrogen production through photocatalytic water splitting (PWS) over the past five decades. However, achieving commercially viable solar-to-hydrogen conversion efficiency in PWS systems remains elusive. These face intrinsic and extrinsic challenges, such as inadequate light absorption, insufficient charge separation, limited redox active sites, low surface area, scalability issues practical designs. To address these issues, conventional strategies including heterojunction engineering, plasmonics, hybridization, lattice defects, sensitization, upconversion processes extensively employed. More recently, innovative hybrid like photonic crystal-assisted polarization field-assisted emerged, which improve absorption separation by harnessing slow photon effect, multiple scattering, piezoelectric, pyroelectric, ferroelectric properties of materials. This review article aims provide a comprehensive examination summary new synergistic approaches, integrating plasmonic effects, processes, crystal photocatalysis. It also explores role temperature suppressing exciton recombination during photothermic highlights emerging effects magnetic fields, periodic illumination, many-body large-hole polaron, anapole excitations, hold significant potential advance technology facilitate renewable generation.
