Sustainable hydrogen production by molybdenum carbide-based efficient photocatalysts: From properties to mechanism. Adv Colloid Interface Sci 2020; 279:102144. [PMID: 32222608 DOI: 10.1016/j.cis.2020.102144] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2019] [Revised: 03/13/2020] [Accepted: 03/17/2020] [Indexed: 12/28/2022]
Abstract
Hydrogen is considered to be a promising energy carrier to solve the issue of energy crisis. Molybdenum carbide (MoxC) is the typical material, which has similar properties of Pt and thought to be an attractive alternative to noble metals for H2 evolution. The study of MoxC as alternative catalyst for H2 production is almost focused on electrocatalytic field, while the application of MoxC as a co-catalyst in photocatalytic H2 evolution has received in-depth research in recent years. Particularly, MoxC exhibits significant enhancement in the H2 production performance of semiconductors under visible light irradiation. However, a review discussing MoxC serving as a co-catalysts in the photocatalytic H2 evolution is still absent. Herein, the recent progress of MoxC on photocatalytic H2 evolution is reviewed. Firstly, the preparation methods including chemical vapor deposition, temperature programming, and organic-inorganic hybridization are detailly summarized. Then, the fundamental structure, electronic properties, and specific conductance of MoxC are illustrated to illuminate the advantages of MoxC as a co-catalyst for H2 evolution. Furthermore, the different heterojunctions formed between MoxC and other semiconductors for enhancing the photocatalytic performance are emphasized. Finally, perspectives regarding the current challenges and the future research directions on the improvement of catalytic performance of MoxC-based photocatalysts are also presented.

Abstract
The support influenced the carbide phase obtained so that a higher ratio of defective carbon favoured the formation of β-Mo2C phase vs. MoOxCy. Redox transformations during the reaction might be responsible of the transformation of β-Mo2C into MoOxCy.

Abstract
Transition metal carbides are versatile materials for diverse industrial applications including catalysis, where their relatively low cost is very attractive. In this work, we present a rather extensive density functional theory study on the energetics of adsorption of a selection of atomic and molecular species on two Mo terminations of the CdI2 antitype phase of Mo2C. Moreover, the coadsorption of CO in the presence of preadsorbed metal atoms and its dissociative adsorption in the absence and presence of preadsorbed Pt and K were investigated. By using CO as a probe to understand the structural/electronic effects of the preadsorption of the metal atoms on the Mo2C(001) surface, we showed that K further enhances CO adsorption/activation on the surface, in contrast to the precious metals considered. Moreover, it was observed that the presence of both Pt and K stabilizes the transition state for the C-O bond dissociation, lowering the activation barrier for the dissociation of the C-O bond by about 0.3 and 0.4 eV, respectively.

Abstract
The interfacial interaction of uranium mononitride (UN) with water from the environment unavoidably leads to corrosion of nuclear fuels, which affects a lot of processes in the nuclear fuel cycle. In this work, the microscopic adsorption behaviors of water on the UN(001) surface as well as water dissociation and accompanying H2 formation mechanisms have been investigated on the basis of DFT+U calculations and ab initio atomistic thermodynamics. For adsorption of one H2O monomer, the predicted adsorption energies are -0.88, -2.07, and -2.07 eV for the most stable molecular, partially dissociative, and completely dissociative adsorption, respectively. According to our calculations, a water molecule dissociates into OH and H species via three pathways with small energy barriers of 0.78, 0.72, and 0.85 eV, respectively. With the aid of the neighboring H atom, H2 formation through the reaction of H* + OH* can easily occur via two pathways with energy barriers of 0.61 and 0.36 eV, respectively. The molecular adsorption of water shows a slight coverage dependence on the surface while this dependence becomes obvious for partially dissociative adsorption as the water coverage increases from 1/4 to 1 ML. In addition, based on the "ab initio atomistic thermodynamic" simulations, increasing H2O partial pressure will enhance the stability of the adsorbed system and water coverage, while increasing temperature will decrease the H2O coverage. We found that the UN(001) surface reacts easily with H2O at room temperature, leading to dissolution and corrosion of the UN fuel materials.
