<p style="text-align: justify;">Photoelectrochemical (PEC) water splitting is one of the sustainable ways to convert abundant solar energy into solar fuel (hydrogen) with zero carbon dioxide emissions. Herein, multidimensional nano-heterostructures based photoelectrodes are employed for PEC water splitting where the multi-layered two-dimensional (2D) structure of MoS<sub>2</sub> and MoO<sub>3</sub> are coupled separately on the well-aligned arrays of one-dimensional (1D) ZnO nanorods template, with the expected effective synergic effects. The advantages of catalytically active sites of the 2D layered structure of transition-metal dichalcogenides/oxides are combined with the distinctive dimensionality-dependent phenomena of 1D structure for photoelectrochemical water splitting. A low onset potential and boosted broadband light absorption is evinced by the ZnO/MoS<sub>2</sub> and ZnO/MoO<sub>3</sub> photoanodes, with significantly high photocurrent densities of 2.04 and 0.67 mA cm<sup>−2</sup> at 1.23 V versus reversible hydrogen electrode, thereby enhancing the photocurrent up to 334% and 43%, respectively, compared to that of pristine ZnO nanorods. Consequently, photoanodes also exhibit enhanced applied bias photon-to-current conversion efficiency, owing to superior spatial photo-induced exciton separation and transportation triggered by favourable interfacial band alignment at 2D−1D heterointerfaces. Moreover, favourable band alignment promotes hole transportation at the heterostructure/electrolyte interface and boost the surface oxygen evolution reaction, leading to enhanced photoelectrochemical performance.</p>
