摘要: Abstract With the advent of nanotechnology there has been a resurge interest in α -Fe2O3, as suitable candidate for photoelectrochemical (PEC) splitting water to generate hydrogen. This paper describes enhanced PEC behaviour nanostructured -Fe2O3 thin films modified by various techniques. Nanostructured film/pellets prepared techniques and dopants were investigated their response. Thin spray pyrolysis having particle size 20–30 nm exhibited better photoresponse compared sol–gel methods, which further improved on doping with Zn. These (i) depositing Zn dots surface using thermal evaporation method (ii) irradiating it 170 MeV Au 13 + ions. When used electrode cell, significant increase these observed, details are discussed.
