Catalytic ozonation of pharmaceutical compounds using carbon-based catalysts Catal. Commun. (IF 3.7) Pub Date : 2024-02-06 C.A. Orge, C.A.L. Graça, J. Restivo, M.F.R. Pereira, O.S.G.P. Soares
Catalytic ozonation has become one of the most promising technologies for wastewater treatment due to its high efficiency in the removal of organic pollutants. Three carbon materials (carbon nanotubes, graphene oxide and activated carbon) and five pharmaceutical compounds were selected for this study. All tested parent pollutants were easily degraded by single ozonation. In terms of mineralization

Hydrothermally prepared unactivated bean sprouts biochar supported CdS with significantly enhanced photocatalytic hydrogen evolution activity Catal. Commun. (IF 3.7) Pub Date : 2024-02-02 Lili Zhang, Chunyan Zhang, Jianjun Li, Keyuan Sun, Jindi Zhang, Mengyang Huang, Jiaqiang Wang
Unactivated bean sprout () biochar (BSB) supported cadmium sulfide composites (CdS/BSB) were prepared by hydrothermal combined with freeze-drying without adding any activation agent. The structure and morphology have been characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM) in detail, respectively. CdS/BSB(5:4) with a mass ratio of CdS to BSB of 5:4 had the highest photocatalytic

Preparation and photocatalytic properties of WSe2/BiVO4 p-n heterojunction photocatalytic materials Catal. Commun. (IF 3.7) Pub Date : 2024-01-30 Zhihua Xia, Xingang Wang, Kai Liu, Haoyun Wang, Yingqi Wang, Wenxin Lu, Deyi Jiang, Haq Nawaz Abbasi, Zechong Guo, Wuxiang Zhang, Hongliang Dai
The 2D transition metal WSe2, a strong photocatalyst, was combined with BiVO4 to create a p-n heterojunction photocatalyst using a hydrothermal process. The resulting 10% WSe2/BiVO4 (in the synthesized material, the mass ratio of WSe2 to BiVO4 is 1:10) composite showed impressive 94.5% efficiency in Methylene Blue (MB) degradation under visible light. Even after eight cycles, it maintained a 72% degradation

The role of immobilization supports for light-assisted Suzuki coupling reaction with low-loading Pd nanocatalyst Catal. Commun. (IF 3.7) Pub Date : 2024-01-29 Bongseok Kim, Hyekyung Cho, Yuwon Jeon, Seunghyun Chun, Bolormaa Bayarkhuu, Jeehye Byun, Hyosun Lee
This work investigates the impact of immobilization supports on the performance of Pd nanocatalysts in light-induced Suzuki coupling reactions by utilizing two model supports, mesoporous silica (SBA-15) and covalent triazine framework (CTF-Ph). Despite comparable Pd loading (0.3–0.5 wt%) and chemical states, under visible light illumination, Pd/CTF-Ph demonstrated a remarkable 40% reduction in activation
