Abstract
Metal-organic framework (MOF)-based heterostructures have aroused widespread interest owing to their extensive compositional tunability and interesting catalytic properties. However, the precise edge-oriented growth of transition metal compounds at the edges of 2D MOFs to construct edge mode heterostructures remains a great challenge due to their inherent thermodynamic instability. Here, edge-oriented growth of Ni2P at the edges of a 2D Ni-MOF was achieved for the first time by precisely tuning the phosphorus source content and phosphating temperature. Owing to the formation of the edge mode Ni-MOF/Ni2P heterostructure, the as-prepared heterostructure showed upregulated d-band center, more robust 4-nitrophenol (4-NP) adsorption capacity, lowered energy barrier of the rate-determining step (RDS), and higher specific surface area, resulting in the best performance of the hydrogenation reduction of 4-NP to 4-aminophenol (4-AP) in the presence of non-precious metal catalysts.

Bide Y, Jahromi NN. Nitrogen and sulfur dual doped porous carbon as metal-free catalyst for oxidative degradation of 4-nitrophenol by persulfate activation. Sci Rep 2023; 13:1212. [PMID: 36681770 PMCID: PMC9867720 DOI: 10.1038/s41598-023-28470-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2022] [Accepted: 01/18/2023] [Indexed: 01/22/2023] Open
Abstract
The replacement of metals in catalytic processes is highly demanded to improve sustainability and economic growth. Poor stability and metal leaching are the main drawbacks of metal-based catalytic reactions. This work represented the use of nitrogen and sulfur-co-doped mesoporous carbon material ((N, S)-MPC) as a metal-free catalyst for the degradation of 4-nitrophenol (4-NP) as a priority pollutant announced by the Environmental Protection Agency through the persulfate-based advanced oxidation process. A low amount of (N, S)-MPC catalyst (0.3 g/L) exhibited superior performance for the degradation of 4-NP within 3 h at room temperature and unadjusted pH. The COD removal was calculated to be 76% using (N, S)-MPC catalyst. Interestingly, the degradations kinetics of 4-NP followed the zero-order kinetics with the rate constant of 0.505 min-1. The radical quenching experiment was accomplished to investigate the activation pathway of degradation. A real sample from an oil and gas company was treated with the (N, S)-MPC catalyst, which showed excellent total decontamination of 61%. The recyclability and stability of the catalyst have been evaluated for three runs. Owing to the obvious benefits such as high efficiency, metal-free nature, and recyclability, the presented catalyst can improve pollutant removal from aqueous media and practical environmental remediation.

Abstract
The accumulation and self-aggregation of nanosheets have been effectively inhibited. The interlamellar cobalt hydroxide nanostructures ensure efficient electron transfer. MXene as a conductive substrate improves electron transfer significantly.
