摘要: Abstract The production of H2 via photocatalytic water splitting reaction has attracted a great attention as clean and renewable energy for next generation. Despite tremendous efforts, the present challenge materials scientist is to develop highly active photo catalysts at low cost. This article reports synthesis TiO2-reduced graphene oxide hybrid nanomaterials through ionothermal method using functionalized ionic liquid enhanced hydrogen generation reaction. structural morphological properties samples were investigated by XRD, Raman spectroscopy, TG-DTA, UV–vis spectroscopy TEM. A substantial increase evolution was observed nanomaterials. due high migration efficiency photo-induced electrons inhibition charge–carrier recombination electronic interaction between TiO2 reduced oxide. i.e, acts an electron-acceptor which effectively hinders electron–hole pair TiO2.
