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

Tandem catalysis over disparate active sites is frequently designed to promote the catalytic efficiency for industrial reactions. Herein, a built-in tandem system in a single hierarchical porous catalyst is constructed for vinyl chloride production from ethylene dichloride and acetylene cascade. Using a pore-selective filling strategy, Ru, CuRu, and AuRu components are sequentially confined in the macro-, meso- and micropores of carbon material. Mechanism study shows that ethylene-dichloride dehydrochlorination occurs on macropore Ru sites, generating vinyl chloride. H and Cl radicals react with acetylene on mesopore CuRu sites, and the residual acetylene is hydrochlorinated over micropore AuRu sites. The stronger acetylene adsorption of CuRu and AuRu in a VCM-rich atmosphere enables acetylene conversion near the thermodynamic limit and stable operation for 1200 h on stream. This built-in tandem catalysis in hierarchical pores provides a general paradigm for cascade reactions in a single porous catalyst.
