Abstract

Introduction

We have explored the impact of the incorporation of nanoporous carbons from varied physicochemical features as additives to Bi₂WO₆ for the photocatalytic degradation of a dye. Previous data at lab-scale under artificial solar light has revealed that the composition and acidic character of the carbon additive are important parameters in the performance of Bi₂WO₆/carbon catalysts, and that the carbon component improved the conversion of the dye and accelerated the degradation rate. The presence of the carbon component also lowered the toxicity of the treated solution after short irradiation periods. The aim of this study was to evaluate the eventual scaling up of the best performing photocatalyst by analyzing the photodegradation of the dye under real solar conditions in a compound parabolic collector (CPC) pilot plant in Bio Bio region in Chile.
