Photocatalytic Dinitrogen Fixation with Water on Bismuth Oxychloride in Chloride Solutions for Solar-to-Chemical Energy Conversion

Ammonia is an indispensable chemical. Photocatalytic NH3 production via dinitrogen fixation using water by sunlight illumination under ambient conditions is a promising strategy, although previously reported catalysts show insufficient activity. Herein, we showed that ultraviolet light irradiation of a semiconductor, bismuth oxychloride with surface oxygen vacancies (BiOCl-OVs), in water containing chloride anions (Cl-) under N2 flow efficiently produces NH3. The surface OVs behave as the N2 reduction sites by the photoformed conduction band electrons. The valence band holes are consumed by self-oxidation of interlayer Cl- on the catalyst. The hypochloric acid (HClO) formed absorbs ultraviolet light and undergoes photodecomposition into O2 and Cl-. These consecutive photoreactions produce NH3 with water as the electron donor. The Cl- in solution compensates for the removed interlayer Cl- and inhibits catalyst deactivation. Simulated sunlight illumination of the catalyst in seawater stably generates NH3 with 0.05percent solar-to-chemical conversion efficiency, thus exhibiting significant potential of the seawater system for artificial photosynthesis.

Novel N-Black In2O3?x/InVO4heterojunction for efficient photocatalytic fixation: synergistic effect of exposed (321) facet and oxygen vacancy

Utilizing semiconductors to catalyze the conversion of N2to NH3has brought great promise in alleviating the issue of energy shortage. However, the wide band gap and high recombination rate of photogenerated (e?/h+) charge restrict their photocatalytic efficiency. Herein, a novel catalyst, N-Black In2O3?x/InVO4was developed by coupling InVO4nanosheets into defect-rich N-Black In2O3?xnanorods to construct multiple heterojunctions using the NH2-MIL-68(In) metal-organic-framework as a template. The N-Black In2O3?x/InVO4multiple heterojunctions with oxygen vacancies could expand the light absorption range, act as electron trap centers, promote the separation of photogenerated carriers, and significantly improve the adsorption as well as activation of N2. Density functional theory (DFT) calculations revealed that the exposed (321) planes of the N-Black In2O3?xpossess a higher surface energy than the (222) planes, which indicates that the exposed (321) planes can adsorb more N2molecules and transform them into NH3molecules. Consequently, owing to the efficient separation of photogenerated carriers, the nitrogen fixation rate of the N-Black In2O3?x/InVO4heterostructure was as high as 2.07 mmol g?1h?1without any organic scavengers and precious-metal cocatalysts, which was 20.7, 2.4, 2.1, and 1.8 times that of NH2-MIL-68(In), N-In2O3, InVO4, and N-Black In2O3?x, respectively.
