Abstract

Oxidative dehydrogenation of propane (ODHP) is a reaction with significant practical significance. As for the industrial application of ODHP, it is challenging to achieve high activity and high propylene selectivity simultaneously. In this study, to overcome this obstacle, we designed a series of Cu/BN catalysts with unique morphologies for establishing a photothermal ODHP system with high efficiency and selectivity. Characterization and evaluation results revealed that Cu/BN-NS and Cu/BN-NF with enlarged specific surface areas exhibited higher catalytic activities. The localized surface plasmon resonance (LSPR) effect of Cu nanoparticles further enhanced the photothermal catalytic performances of Cu/BN catalysts under visible light irradiation. To the best of our knowledge, it is the first time to establish a BN-based photothermal ODHP catalytic system. This study is expected to pave pathways to realize high activity and propylene selectivity for the practical application of ODHP.

摘要

丙烷氧化脱氢（ODHP）是一个具有重大实际意义的反应。至于ODHP的工业应用，要同时实现高活性和高丙烯选择性具有挑战性。在本研究中，为克服这一障碍，我们设计了一系列具有独特形貌的Cu/BN催化剂，以建立一个高效且选择性高的光热ODHP体系。表征和评价结果表明，具有更大比表面积的Cu/BN-NS和Cu/BN-NF表现出更高的催化活性。铜纳米颗粒的局域表面等离子体共振（LSPR）效应进一步增强了Cu/BN催化剂在可见光照射下的光热催化性能。据我们所知，这是首次建立基于BN的光热ODHP催化体系。本研究有望为实现ODHP实际应用中的高活性和丙烯选择性铺平道路。
