主要业绩

半导体气体传感技术是获取气体信息的重要手段，在疾病诊断、公共安全、国防军工等领域具有重要意义。然而，实现复杂体系下超低浓度目标气体分子的精准、快速检测仍存在重大挑战。半导体材料表界面性质的精准调控是解决这一问题的关键。近年来，我们提出了一种普适性的金属-多酚自模板合成策略，实现了高活性介孔半导体纳米球气敏材料的可控制备，开发了系列小型化、手持式气体传感器；提出了孔道界面原子级精准修饰贵金属增敏剂的策略，实现了超低浓度目标气体分子的快速、精准检测，揭示了气体传感信号增强的分子机制；发展了气敏材料孔道微环境调控新策略，实现了新应用场景下气体分子的高效检测，拓展了半导体气体传感器在疾病诊断、公共安全等领域的应用范围。迄今，发表SCI论文105篇，被引10000余次，H因子50。近5年，以通讯作者（含共同）在Angew. Chem. Int. Ed.、ACS Nano、Nano Lett.、Mater. Horiz.、Chem. Sci.、ACS Sens.、Anal. Chem.等期刊发表论文31篇。授权中国发明专利7项。主持国家自然科学基金面上、青年项目、陕西省重点研发项目、西安市科技局农业技术攻关项目、企业横向课题等科研项目10余项。获中国分析测试协会科学技术奖一等奖（排5）、上海市研究生优秀成果（学位论文）奖（排1）。入选陕西省高层次人才引进计划、小米青年学者。担任Chinese Chemical Letters、Biosensors期刊编委。担任J. Am. Chem. Soc.、Angew. Chem. Int. Ed.、Adv. Mater.等期刊的审稿人。
