Abstract

Abstract The study of hydrogen evolution reaction and oxygen evolution reaction electrocatalysts for water electrolysis is a developing field in which noble metal-based materials are commonly used. However, the associated high cost and low abundance of noble metals limit their practical application. Non-noble metal catalysts, aside from being inexpensive, highly abundant and environmental friendly, can possess high electrical conductivity, good structural tunability and comparable electrocatalytic performances to state-of-the-art noble metals, particularly in alkaline media, making them desirable candidates to reduce or replace noble metals as promising electrocatalysts for water electrolysis. This article will review and provide an overview of the fundamental knowledge related to water electrolysis with a focus on the development and progress of non-noble metal-based electrocatalysts in alkaline, polymer exchange membrane and solid oxide electrolysis. A critical analysis of the various catalysts currently available is also provided with discussions on current challenges and future perspectives. In addition, to facilitate future research and development, several possible research directions to overcome these challenges are provided in this article. Graphical Abstract

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Primary variables impacting electrocatalyst atom rearrangements include surface roughness, identification of catalytic center sites, phase transitions, and on the catalytic surface during electrochemical processes.

    “The primary variables that impact the characteristics of electrocatalyst atom rearrangements include the influence of surface roughness, identification of catalytic center sites, phase transitions, and on the catalytic surface that occur during electrochemical processes [62,63].”

    From Silica Aerogels as a Promising Vehicle for Effective Water Splitting for Hydrogen Production (2025) · cites this paper as [62]

    Section 4.1 discusses how morphology affects electrocatalytic performance, and section 4.3 says active centres cannot yet be identified accurately. Neither passage addresses atom rearrangements or identifies surface roughness, active-site identification, and phase transitions as variables affecting them. Searches for atom rearrangements and surface reconstruction did not find a passage establishing that claim. (LLM, conf=0.70)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
