Thiophene-like sulfides present in fuel oil release sulfur oxides (SO) during combustion, which pose significant risks for both environmental sustainability and public health. Adsorption desulfurization (ADS) has garnered considerable attention because of its mild operating conditions, low production costs, and minimal impact on the octane number of fuels. Metal-organic frameworks used as desulfurizing adsorbents provide several advantages, including a high specific surface area and easily adjustable structures. Here, we synthesized the micro/mesoporous adsorbent CeO@HP-HKUST-1 (CeO@Hierarchical Porous-Hong Kong University of Science and Technology-1) through the hybridization of salicylic acid (SA) using a solvothermal method. We assessed the adsorption performance ofCeO@HP- HKUST-11.5for benzothiophene and thiophene through batch and breakthrough adsorption experiments. The adsorption capacities for thiophene and benzothiophene were measured at 21.2 mg S/g and 35.3 mg S/g, respectively. Remarkably, in competitive toluene experiments, the adsorption capacity for benzothiophene remained significant at 28.9 mg S/g, due to enhanced Ce-S bonding interactions and the exposure of unsaturated metal centers of Cu. Additionally, regeneration experiments demonstrated that CeO@HP-HKUST-1 retained excellent adsorption capacities after four cycles. These findings highlight the potential of CeO@HP-HKUST-1 as an effective adsorbent for desulfurization applications.

With the rapid development of adsorbents for removal of elemental mercury (Hg) from coal combustion flue gas, the preparation of adsorbents with superior performance, lower cost and environmental friendliness remains an important challenge. An incipient wetness impregnation method followed by in-situ selenization was used to load copper selenide (CuSe) onto the surface of optimal magnetic biochar (OMBC). The results showed that CuSe significantly enhanced the Hg removal performance of the OMBC, and CuSe loading ratio of 10 % (10CuSe/OMBC) had the best Hg removal performance.

The removal of boron from wastewater is essential for protecting environmental health and supporting sustainable urbanization by preventing toxic accumulation in ecosystems. Existing adsorption technologies face challenges such as limited capacity, slow kinetics, high regeneration costs, and reduced efficiency due to adsorbent saturation. This study develops an eco-friendly adsorbent (CGCNF beads) by modifying chitosan nanofibers with d-(+)-glucono-1,5-lactone (GL) to enhance boron removal.

The removal of SO from flue gas remains a challenge. Adsorption-based separation of SO using porous materials has been proposed as a more energy-efficient and cost-effective alternative to more traditional methods such as cryogenic distillations. Here we report a flexible hydrogen-bonded organic framework (HOF-NKU-1) that enables the sieving of SO through the guest-adaptive response and shape-memory effect of the material.

In this work, groundnut shell-derived mesoporous carbons, synthesized by one-step carbonization at different temperatures in presence of potassium hydroxide, were used for desulfurization studies involving dibenzothiophene, benzothiophene and thiophene. The pore formation and corresponding surface area of synthesized mesoporous carbon was governed by carbonization temperature as it increased from 600 to 900 °C. The carbon synthesized at carbonization temperature of 800 °C, that is GN-800, showed highest surface area (1192 m/g) and pore volume (0.
