Abstract The controlled synthesis of nanohybrids composed of noble metals and metal oxides have received considerable attention for applications in photocatalysis, solar cells, drug delivery, surface enhanced Raman spectroscopy, and various important areas. Among various metal oxides, cuprous oxide (Cu2O), an important p-type semiconducting material with a unique optical and electrical property, is an appealing candidate for solar energy conversion, sensors, photo-catalytic degradation, and coherent propagation of excitons. In addition, it has an attractive property to absorb visible light region. Two-dimensional semiconductors such as MoS2 are an emerging material family with wide-ranging potential applications in electronics, optoelectronics, and energy harvesting. MoS2 is easy to use in nanotechnology and can be made as a single layer. The MoS2 of the single-layer has a high surface area, which improves the photocatalytic and photovoltaic efficiency in visible light region. Herein, we have developed a facile synthetic method for the preparation of cuprous oxide nanocubes on molybdenum disulfide nanosheets. These are used for hydrogen production by water splitting. The new heterostructure materials have better catalytic activity than conventional ones.
