Abstract Nanosphere and nanotube titanates (TNT) amalgamated with different graphene oxide (GO) ratios synthesized by one pot microwave irradiation route have presented excellent potential towards hydrogen production photoelectrochemically under solar irradiation. The hybrid nanospherical array of the 50TNT-50GO photocatalyst showed a current density equal 9.2 mA cm-2 at a bias of 0.20 V vs. RHE exceeding those of the nanotubes 30TNT-70GO (4.0 mA cm-2 at 0.38 V) and 10TNT-90GO (3.7 mA cm-2 at 0.4 V). The former electrode also exhibits small Tafel slope value (40 mV dec-1), decreased particle diameter (7 nm), decreased band gap (2.6 eV) and high rate of charges transfer. The hybrid structure elucidation carried out using TEM-SAED, XRD, N2 adsorption, UV-Vis, FTIR and PL techniques approved the interfacial interaction between TNT and GO(RGO) networks that was responsible for the high quantum yield, delay of charges recombination beside the increase in the pore volume.

Two Phases

A nanocomposite photocatalyst consisting of deposited CdS nanoparticles on TiO2 nanosheets was fabricated by a simple one-pot method. The contact between two phases was maximized by making a composite structure of TiO2 nanosheet decorated with CdS nanoparticles. The composite photocatalyst showed higher photoactivity for hydrogen production from aqueous Na2S/Na2SO3 solution and decomposition of methylene blue under visible light irradiation (λ ≥ 420 nm) compared with single component CdS nanoparticles or a physical mixture of CdS nanoparticles and TiO2 nanorods. The intentional formation of nanoscale heterojunctions between two phases appears beneficial for inducing an efficient electron-hole separation.
