Using rice husk as a silicon source, this work investigated the effect of rice-husk addition on the vitrification of landfilled-waste slag and the solidification behavior of heavy metals. The results demonstrated that the incorporation of rice husk (5%−10%) lowered the flow temperature of the slag and effectively suppressed heavy-metal leaching. Specifically, the leaching concentrations of Cr and Zn decreased from 41.60 and 108.00 mg/L to 5.89 and 7.10 mg/L, respectively. The active SiO<sub>2</sub> introduced by rice husk promoted the formation of highly polymerized siloxane networks (Q<sup>3</sup>, Q<sup>4</sup>), which inhibited gasification-induced migration of heavy metals and enhanced physical encapsulation of them. Concurrently, it facilitated the incorporation of Zn<sup>2+</sup>, Cr<sup>3+</sup> and Cu<sup>2+</sup> <em>via</em> substitution or solid-solution mechanisms into stable mineral phases such as Zn<sub>2</sub>SiO<sub>4</sub> and CuFe<sub>2</sub>O<sub>4</sub>, immobilizing them in garnet and spinel structures.

In this study, density functional theory (DFT) calculations were employed to conduct a comparative analysis of the MSR reaction mechanism on PdCu(111) and PtCu(111) bimetallic surfaces. The investigation unveiled the underlying mechanism by which alloying modulates reaction pathways and overall catalytic performance. Notably, Cu sites were found to stabilize adsorption of OH and CH<sub>2</sub>O species, whereas Pd/Pt sites exhibited a preferential affinity for CO molecule. This spatial site separation facilitates progression along the formate pathway. PdCu(111) demonstrated superior overall catalytic performance compared to PtCu(111), with water dissociation identified as the rate-determining step (RDS), featuring an activation energy of only 0.74 eV. The bimetallic synergy breaks the inherent contradiction between the activity and selectivity of monometallic catalysts: Cu sites serve as a source of hydroxyl groups, while Pd/Pt sites enhance C–H bond cleavage efficiency, ultimately enabling high methanol conversion alongside low CO formation.

Ca-based dry desulfurization presents a promising technology for biomass boiler flue gas purification due to its compact structure, low capital investment and simple operation and maintenance. However, it is generally limited by the low adsorbent utilization and insufficient desulfurization efficiency. Herein, this study developed a novel Ca-Mn composite adsorbent through a synergistic strategy integrating F127 surfactant to optimize dispersion and Mn loading to enhance oxidation efficiency. The resulting adsorbent not only significantly increased the breakthrough sulfur capacity of the Ca-based material but also markedly improved the synergistic removal of Hg<sup>0</sup>. It was demonstrated that the introduction of Mn elements and F127 effectively suppressed the agglomeration of Ca(OH)<sub>2</sub> crystallites and induced an oxygen vacancy-rich structure, while simultaneously optimizing the pore structure of the adsorbent. The modified adsorbent exhibited the enlarged specific surface area and pore volume, which favored to enhance the reaction mass transfer and effectively prevent the pore blockage and coverage of active sites by desulfurization products. The Mn sites and oxygen vacancies formed catalytic centers, which not only accelerated the desulfurization reaction by promoting SO<sub>2</sub> oxidation but also enabled the adsorbent to couple with Hg<sup>0</sup> catalytic oxidation functionality.
