A surface analysis has been conducted on a series of electrodeposited nickel-phosphorus (Ni-P) alloys containing from 6 to 29 at.% phosphorus, using X-ray photoelectron spectroscopy (XPS) and X-ray excited Auger electron spectroscopy (XAES). No changes in core-level binding energies, Ni2p3/2 and Ni2p1/2, P2p, P2s, or X-ray excited NiLMM and PKLL Auger lines were observed regardless of phosphorus concentration. The only systematic differences observed concerned: (i) the binding energy of the Ni2p satellite peak, (ii) the fine structure of the NiLMM Auger lines, (iii) the percentage of the satellite in the total Ni2p3/2 spectrum and (iv) the valence band density of states in the Ni3d electrons region, all related to the electronic structure of the Ni-P alloys. For the first time, it has been possible to describe and rationalise the influence of (phosphorus) ligand concentration on the electronic structure of nickel-based alloys, using a screening model proposed in the literature for clarifying the role of substituents on the electronic structure of conductor compounds of nickel. As the phosphorus content increases, the number of non-bonding Ni3d electrons decreases. Thus the d-type core-hole screening is less pronounced and the binding energy of the satellite for the final state with a filled Ni4s shell increases.

Catalytic NiO Filter Supported on Carbon Fiber for Oxidation of Volatile Organic Compounds

Carbon-fiber-supported NiO catalytic filters for oxidation of volatile organic compounds were prepared by electroless Ni-P plating and subsequent annealing processes. Surface structure and crystallinity of NiO film on carbon fiber could be modified by post-annealing at different temperatures (500 and 650 o C). Catalytic thermal decompositions of toluene over these catalytic filters were investigated. 500 o C-annealed sample showed a higher catalytic reactivity toward toluene decomposition than 650 o C-annealed one under same conditions, despite of its lower surface area and toluene adsorption capacity. X-ray diffraction and X-ray photoelectron spectroscopy studies suggest that amorphous structures of NiO on 500 o C-annealed catalyst caused the higher reactivity for oxidation of toluene than that of 650 o C-annealed sample with a higher crystallinity.

MXenes have extensive applications due to their different properties determined by intrinsic structures and various functional groups. Exploring different functional groups of MXenes leads to improved performance or potential applications. In this work, we prepared new Ti3C2PBrx (x=0.4‐0.6) MXene with phosphorus functional groups (‐P) through a two‐step gas‐phase reaction. The acquisition of ‐P is achieved by replacing bromine functional groups (‐Br) of Ti3C2Br2 in the phosphorus vapor. After ‐Br is replaced with ‐P, Ti3C2PBrx MXene shows an improved areal capacitance (360 mF cm‐2) at 20 mV s‐1 compared with Ti3C2Br2 MXene (102 mF cm‐2). At a current density of 5 mA cm‐2 after 10000 cycles, the capacitance retention of Ti3C2PBrx MXene has not decreased. The pseudocapacitive enhancement mechanism has been discovered based on the dual redox sites of the functional groups ‐P and Ti.
