Systematic optimization of the Bi:Pd molar ratio, support and catalyst calcination temperatures, H2 reduction temperature, and impregnation sequence established clear structure–activity relationships. X-ray diffraction (XRD) and high-resolution transmission electron microscopy (HRTEM) revealed the formation of a Pd–Bi solid solution with uniformly dispersed nanoparticles (~ 3.5 nm), and X-ray photoelectron spectroscopy (XPS) indicated a small positive shift (~ 0.3 eV) in the Pd 3d binding energy upon Bi incorporation, tentatively consistent with Pd–Bi electronic interaction. Under optimized conditions (60 °C, pH 9.0, O2 atmosphere), the catalyst achieved near-complete glucose conversion with > 99% selectivity toward gluconic acid, and maintained high performance over 30 consecutive reaction cycles with only a minor decline to 95% conversion. The synthesized sodium gluconate was further evaluated for postharvest preservation of chili peppers (Capsicum annuum L.). Using a Comprehensive Quality Index (CQI) model integrating six quality indicators, a 0.1% (w/v) sodium gluconate (SG) treatment was identified as the hormetic optimum, which significantly delayed senescence by reducing respiratory intensity and upregulating peroxidase (POD) activity, thereby preserving vitamin C and chlorophyll levels over a 21-day storage period.","PeriodicalId":750,"journal":{"name":"Reaction Kinetics, Mechanisms and Catalysis","volume":"139 5","pages":"4497 - 4517"},"PeriodicalIF":2.1,"publicationDate":"2026-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149099243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The adsorption processes were optimized in terms of pH, adsorbent dosage, temperature, and contact time. Among the synthesized nano adsorbents, Fe NPs demonstrated the highest NPX removal efficiency and maximum adsorption capacity (qmax) (78.4%, qmax = 73.61 mg/g) under optimum conditions, whereas CuO NPs exhibited the lowest removal performance and maximum adsorption capacity (61.2%, qmax = 30.76 mg/g). Kinetic modeling revealed that adsorption pathways strongly depend on nanoparticle composition; Ag/Cu NPs showed better agreement with the intraparticle diffusion (IPD) model, whereas Ag, Fe, and CuO NPs followed pseudo-first order (PFO) and pseudo-second order (PSO) kinetics, indicating surface-interaction-driven adsorption mechanisms. Furthermore, isotherm analyses showed that all nanoparticle systems exhibited the best fit with the Freundlich model, confirming heterogeneous multilayer adsorption behavior with partial monolayer adsorption characteristics and intermolecular interaction effects. Overall, the findings demonstrate that Helichrysum arenarium mediated green synthesized NPs, particularly Fe NPs, possess considerable potential as sustainable, environmentally friendly, and efficient nano adsorbents for the remediation of pharmaceutical wastewater pollution.

The effects of various operational parameters, including solution pH, chlorine, pollutant, and catalyst concentrations, as well as solution temperature, were systematically examined using the removal of Basic Yellow 28 (BY28) as a model pollutant. Furthermore, mathematical models were established to reliably predict the BY28 degradation rate under different operational conditions. Under optimized conditions (150 µM chlorine, solution pH 3, and a BY28 dose of 20 mg L−1), BY28 removal increased with agitation speed, reaching 87.5% at 400 rpm, while solution temperature exerted a negligible influence. Under these conditions, reactive chlorine species and hydroxyl radicals played dominant roles, with a comparatively lower contribution from ferryl species. The chlorine activation mechanism was discussed, with particular emphasis on the influence of water matrices. The performance of the hybrid SWI/chlorine system was adversely affected by the presence of surfactants (Tween 80, Tween 20, Triton X-100, and SDS) and inorganic salts (Na2SO4, KBr, NaNO3, and NaNO2), with the inhibitory effect being more pronounced for the latter. Nevertheless, a positive impact was observed in the presence of NaCl. A total organic carbon (TOC) reduction of approximately 40% was obtained under optimal conditions.
