Abstract
An ultrathin MoS2 was grown on CdS nanorod by a solid state method using sulfur powder as sulfur source for photocatalytic H2 production. The characterization result reveals that the ultrathin MoS2 nanosheets loaded on CdS has a good contact state. The photoelectrochemical result shows that MoS2 not only are beneficial for charge separation, but also works as active sites, thus enhancing photocatalytic activity. Compared with pure CdS, the photocatalytic activity of MoS2 loaded CdS was significantly improved. The hydrogen evolution rate on m(MoS2): m(CdS) = 1: 50 (m is mass) reaches 542 μmol/h, which is 6 times of that on pure CdS (92 μmol/h). This work provides a new design for photocatalysts with high photocatalytic activities and provides a deeper understanding of the effect of MoS2 on enhancing photocatalytic activity.
期刊介绍：
Frontiers in Energy, an interdisciplinary and peer-reviewed international journal launched in January 2007, seeks to provide a rapid and unique platform for reporting the most advanced research on energy technology and strategic thinking in order to promote timely communication between researchers, scientists, engineers, and policy makers in the field of energy.
Frontiers in Energy aims to be a leading peer-reviewed platform and an authoritative source of information for analyses, reviews and evaluations in energy engineering and research, with a strong focus on energy analysis, energy modelling and prediction, integrated energy systems, energy conversion and conservation, energy planning and energy on economic and policy issues.
Frontiers in Energy publishes state-of-the-art review articles, original research papers and short communications by individual researchers or research groups. It is strictly peer-reviewed and accepts only original submissions in English. The scope of the journal is broad and covers all latest focus in current energy research.
High-quality papers are solicited in, but are not limited to the following areas:
-Fundamental energy science
-Energy technology, including energy generation, conversion, storage, renewables, transport, urban design and building efficiency
-Energy and the environment, including pollution control, energy efficiency and climate change
-Energy economics, strategy and policy
-Emerging energy issue
