FexP/biochar composites induced oxygen-driven Fenton-like reaction for sulfamethoxazole removal: Performance and reaction mechanism

Highly Efficient Peroxymonosulfate Activation by Surface Oxidized Nickel Phosphide with Dual Active Sites

“…Nickel phosphide (Ni 2 P), formed by the alloying of nickel and phosphorus, has recently developed as a new class of nonprecious electrocatalyst for water splitting because of the charged nature of nickel and phosphorus in Ni 2 P. 13,14 The unique electronic structure allows it to act as a PMS activator for the catalytic degradation of organic pollutants, which has been demonstrated in other metal phosphide-based PMS activators, such as CoP, 15 Cu 3 P, 16 Co 0.59 Fe 0.41 P, 17 and Fe x P. 18 In this work, we report a chemical transformation synthesis of surface oxidized Ni 2 P and demonstrate its high performance toward the highly efficient PMS activation. The Ni 2 P with its charged nature of nickel (Ni δ+ ■ EXPERIMENTAL SECTIONS Materials.…”

Activating the Basal Plane of 2H-MoS2 by Doping Phosphor for Enhancement in the Photocatalytic Degradation of Organic Contaminants

“…Several degradation intermediates were found, as shown in Figures S12–S16. According to the detected intermediates and reported studies, the primary degradation path is as follows: (1) the S–N bond was attacked by ROS; (2) the oxidation reaction occurred on the amino group on the aromatic ring; (3) a hydroxylation reaction was performed on the C2 or C6 of SMX. Further, though other high charge-mass ratio signals are hard to distinguish, it is believed that the N-centered intermediates are not difficult to couple with ROS molecules for the following degradation …”

Copper phosphide–phosphorus (Cu3P/P) hybrid nanomaterials: an in situ dioxygen activator in ambient aqueous conditions for advanced oxidation process

“…[22][23][24] In view of their oxygen activation ability, MPs (such as Fe x P and Cu x P) have been applied for ROS generation in AOPs recently. 20,21,25,26 Intriguingly, copper phosphide (Cu x P) spontaneously generated ROS through in situ O 2 reduction in a previous report. However, the oxidation efficiency for organic pollutants in the Cu x P suspension was good only under acidic conditions (pH = 3), in which the Cu and P species were leached out, and the activity of Cu x P was gradually reduced in successive degradation cycles.…”

“…Zn 0 and P dÀ in Table 1). [19][20][21] Due to the unique metalloid structure, high electron conductivity and good photoactivity of transition metal phosphides (MPs), MPs have been considered as efficient catalysts or co-catalysts in the electrocatalytic oxygen reduction reaction (ORR) and hydrogen evolution reaction (HER). [22][23][24] In view of their oxygen activation ability, MPs (such as Fe x P and Cu x P) have been applied for ROS generation in AOPs recently.…”
