Gas phase catalytic hydrodechlorination of chlorobenzene over cobalt phosphide catalysts with different P contents

- CoP catalysts are active in the gas phase hydrodechlorination of chlorobenzene.
- The amount of P incorporated determines the catalytic response.
- The catalytic activity followed the trend: CoP > Co2P > Co.
- Conversion, H-spillover species, weak acidity and dispersion are correlated.
