Increasing concern over the safety of consumable products, particularly aquatic due to freshness issues, has become a pressing issue. Therefore, ensuring quality and products is paramount. To address this, dual-mode colorimetric–fluorescence sensor utilizing Ce-MOF as mimic peroxidase detect H2S was developed. prepared by conventional solvothermal synthesis method. catalyzed oxidation 3,3’,5,5’-tetramethylbenzidine (TMB) hydrogen peroxide (H2O2) produce blue oxidized TMB (oxTMB). When dissolved, sulfide (H2S) present in solution, it inhibited catalytic effect caused color solution fade from colorless. This change provided an intuitive indication for detection H2S. Through steady-state dynamic analysis, working mechanism this elucidated. The exhibited pronounced changes colorless, accompanied shift fluorescence none light blue. Additionally, UV–vis absorption demonstrated linear correlation with concentration, ranging 200 2300 µM, high sensitivity (limit detection, LOD = 0.262 μM). Fluorescence intensity also showed correlation, 16 320 selectivity (LOD 0.156 These results underscore sensor’s effectiveness detecting Furthermore, enhanced accuracy fulfilled requirements assessing food safety.

The increase in CO2 emissions has been identified as a core driving factor the intensification of greenhouse effect. In order to achieve dual-carbon vision, research on capture and its catalytic conversion is receiving growing attention. Due high chemical stability itself, traditional separation technologies find it difficult onto catalysts. Currently, using hydrocarbons carriers for reactions most common efficient method. recent years, metal-organic frameworks (MOFs) have shown their irreplaceable importance due unique adjustable controllable pore structures multiple active sites. This study integrates various classification criteria MOFs, proposes cooperative mechanism between metal doping functional groups, also reveals processes. addition, we conducted an in-depth discussion future development continuous-flow microreactor technology provided performance property relationship diagrams MOF series, offering valuable reference material related fields.
