1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Electrochemical water splitting for hydrogen production is an important path for the preparation of green hydrogen. However, the sluggish kinetics and high energy consumption of the anode oxygen evolution reaction (OER) have restricted its development. The hydrazine oxidation reaction (HzOR), with its low theoretical potential, fast kinetics, clean products, and the ability to simultaneously treat hydrazine-containing wastewater, has emerged as an ideal anode reaction to replace OER. Transition metal phosphides (TMPs) have shown noble-metal-like activity in HzOR catalysis due to their tunable d-band electronic structure, abundant active sites, high conductivity, and structural stability, making them highly promising non-noble metal catalysts. However, most existing reviews focus on the catalytic performance of TMPs in general hydrogen evolution reaction (HER)/OER systems or merely briefly mention HzOR as one of many anode reactions. Therefore, this review aims to comprehensively and systematically elaborate on the design strategies of TMPs catalysts for hydrazine-assisted electrolytic water splitting for hydrogen production and their applications in HzOR, deeply discuss the current progress, challenges, and future directions, and provide references for the development and industrial application of low-cost, high-efficiency, and high-stability hydrazine-assisted hydrogen production catalysts.
