摘要

采用水热法合成了一种锰掺杂Y(OH)3/Fe_2O3的高性能甲醛传感器．通过XRD、SEM、EDS和XPS分析了锰掺杂Y(OH)3/Fe_2O3复合材料的结构、形貌以及组成成分．通过表征结果发现，锰元素掺杂Y(OH)3/Fe_2O3使得Y(OH)3/Fe_2O3颗粒分布更加均匀，表面氧空位缺陷增多，有可能提供更多的活性位点来吸附甲醛气体，增强了锰掺杂Y(OH)3/Fe_2O3的气敏性能．气敏测试结果表明：基于锰掺杂Y(OH)3/Fe_2O3复合材料的甲醛传感器相比Y(OH)3/Fe_2O3不仅具有高灵敏度和良好的选择性，而且能够在室温下表现出快速的响应和恢复特性．最后讨论了锰掺杂Y(OH)3/Fe_2O3对甲醛气敏性增强的传感机制，进一步说明基于锰掺杂Y(OH)3/Fe_2O3复合材料的甲醛传感器在实际应用中的潜在价值．

Abstract

A high-performance formaldehyde sensor Mn-doped Y(OH)3/Fe_2O3 was synthesized by hydrothermal method.The structure

morphology and composition of Mn-doped Y(OH)3/Fe_2O3 composites were analyzed by XRD

SEM

EDS and XPS.Through the characterization results

it was found that Mn-doped Y(OH)3/Fe_2O_3made Y(OH)3/Fe_2O3 particle distribution more uniform

and the surface oxygen vacancy defects increase

which provides more active sites to adsorb formaldehyde gas and enhances the gas sensing performance of Mn-doped Y(OH)3/Fe_2O3.In addition

the experiments show that compared with Y(OH)3/Fe_2O3

the formaldehyde sensor based on Mn-doped Y(OH)3/Fe_2O3 composite not only has high sensitivity and good selectivity

but also can exhibit fast response and recovery characteristics at room temperature.Finally

the paper also discusses the enhanced sensing mechanism of Mn-doped Y(OH)3/Fe_2O3 for formaldehyde

which further illustrates the potential value of formaldehyde sensor based on Mn-doped Y(OH)3/Fe_2O3 composite in practical applications.
