MEMBRANES 2022; 12:membranes12040363. [PMID: 35448332 PMCID: PMC9027779 DOI: 10.3390/membranes12040363] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/04/2022] [Revised: 03/23/2022] [Accepted: 03/23/2022] [Indexed: 11/24/2022]
Abstract
Water electrolysis (WE) is a highly promising approach to producing clean hydrogen. Medium-temperature WE (100–350 °C) can improve the energy efficiency and utilize the low-grade water vapor. Therefore, a high-temperature proton-conductive membrane is desirable to realize the medium-temperature WE. Here, we present a polyvinyl chloride (PVC)-poly(4vinylpyridine) (P4VP) hybrid membrane by a simple cross-linking of PVC and P4VP. The pyridine groups of P4VP promote the loading rate of phosphoric acid, which delivers the proton conductivity of the PVC-P4VP membrane. The optimized PVC-P4VP membrane with a 1:2 content ratio offers the maximum proton conductivity of 4.3 × 10−2 S cm−1 at 180 °C and a reliable conductivity stability in 200 h at 160 °C. The PVC-P4VP membrane electrode is covered by an IrO2 anode, and a Pt/C cathode delivers not only the high water electrolytic reactivity at 100–180 °C but also the stable WE stability at 180 °C.

Abstract
The PVP and its derivatives have been broadly applied in polymers, organic
syntheses, and catalysis processes. The crosslinked PVP is a well-known polymer support
for numerous reagents and catalysts. Cross-linked PVPs are commercially available polymers
and have attracted much attention over the past due to their interesting properties
such as the facile functionalization, high accessibility of functional groups, being nonhygroscopic,
easy to prepare, easy filtration, and swelling in many organic solvents. A
brief explanation of the reported applications of PVPs in different fields followed by the
discussion on the implementation of methodologies for catalytic efficiency of PVP-based
reagents in the organic synthesis is included. The aim is to summarize the literature under
a few catalytic categories and to present each as a short scheme involving reaction conditions.
In the text, discussions on the synthesis and the structural determination of some typical polymeric reagents
are presented, and the mechanisms of some organic reactions are given. Where appropriate, advantages
of reagents in comparison with the previous reports are presented. This review does not include patent literature.
