Abstract
Official abstract text for this publication.
The present disclosure provides for methods of phosphidation, catalysts formed from phosphidation, and methods of producing H2.
First claim
Opening claim text (preview).
We claim at least the following: 1. A method of phosphidation, comprising: electroplating of a metal (M) on a substrate using constant current electroplating conducting at a constant current density synthesize a M layer having rugae-like morphology, converting the M to MOOH, and optionally converting the MOOH to M oxide, and converting the MOOH, M oxide, or both to nanocrystalline metal phosphide (MP); wherein M is Fe, and the converting M to MOOH step produces a FeOOH-coated substrate comprising both α-FeOOH and γ-FeOOH. 2. The method of claim 1 , wherein the substrate is a carbon cloth. 3. The method of claim 1 , wherein converting the MOOH, M oxide, or both to nanocrystalline MP includes a vapor phase phosphidation carried out in a two-zone chemical vapor deposition (CVD) furnace, wherein PH 3 vapor reacts with the MOOH, M oxide, or both at a temperature within a range of 250-400° C. 4. The method of claim 3 , wherein the PH 3 vapor is produces by evaporating NaH 2 PO 2 in a first zone of the two-zone CVD furnace. 5. The method of claim 3 , wherein the Ph 3 vapor is brought to the FeOOH-coated substrate in the second zone of the two-zone CVD furnace, and wherein the second zone temperature is maintained within a range of 250-300° C.
