In this study, litchi-like g-C3N4\/In2O3 composites were synthesized by a hydrothermal method and used to develop H2 sensors. The morphology characteristics and chemical composition of the samples were characterized to analyze the gas-sensing properties. Meanwhile, a series of sensors were tested to evaluate the gas-sensing performance. Among these sensors, the sensor based on the 3 wt% g-C3N4\/In2O3 (the mass ratio of g-C3N4 to In2O3 is 3:100) showeds good response properties to H2, exhibiting fast response\/recovery time and excellent selectivity to H2. The improvement in the gas-sensing performance may be related to the special morphology, the oxygen state and the g-C3N4\/In2O3 heterojunction. To sum up, a sensor based on 3 wt% g-C3N4\/In2O3 exhibits preeminent performance for H2 with high sensitivity, fast response, and excellent selectivity.<\/jats:p>","DOI":"10.3390\/s23010148","type":"journal-article","created":{"date-parts":[[2022,12,27]],"date-time":"2022-12-27T02:53:11Z","timestamp":1672109591000},"page":"148","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Highly Selective Gas Sensor Based on Litchi-like g-C3N4\/In2O3 for Rapid Detection of H2"],"prefix":"10.3390","volume":"23","author":[{"given":"Ji","family":"Zhang","sequence":"first","affiliation":[{"name":"State Key Laboratory of Marine Resource Utilization in South China Sea, College of Information and Communication Engineering, Hainan University, Haikou 570228, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xu","family":"Li","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering & Light Industry, Guangdong University of Technology, Guangzhou 510006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qinhe","family":"Pan","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering and Technology, Hainan University, Haikou 570228, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tong","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Electronic and Information Engineering, Qingdao University, 308 Ningxia Street, Qingdao 266071, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qingji","family":"Wang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Marine Resource Utilization in South China Sea, College of Information and Communication Engineering, Hainan University, Haikou 570228, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"182401","DOI":"10.1063\/1.5052666","article-title":"Realization of an H2\/CO dual-gas sensor using CoPd magnetic structures","volume":"113","author":"Liang","year":"2018","journal-title":"Appl.
