Abstract
MoS2 have been regarded as promising catalysts for the hydrogen evolution reaction (HER). However, its poor catalytic performance in neutral and alkaline solution would be problematic for the practical application. Combining semiconductors with metals as Mott-Schottky heterojunctions (MSH) has been regarded as an effective way to improve catalytic activity. Herein, a pH-universal adaptability Mo-MoS2 MSH has been constructed via an in-situ lithiation method. The constructed MSH structure can effectively optimize the sulfur sites' electronic structure with interfacial electron redistribution and enhance the proton adsorption property under all pH conditions. To achieve the current density of 10 mA cm(-2), it only needs overpotentials of 91, 138 and 128 mV in 0.5 M H2SO4, 1.0 M KOH and 1.0 M PBS, respectively, which has been one of the best values of current noble-metal-free electrocatalyst. This work can pave a valuable approach for the design high activity HER electrocatalysts for pH-universal with Pt-like activity.

  • Pretraining has recently greatly promoted the development of natural language processing (NLP)
  • We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
  • We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
  • The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
  • Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
