Facile interfacial modification in a novel TiO2/porphyrin nano-micro hybrid for dual functions of boosting photocatalytic H2 production and methylene blue degradation

•A highly active and cost-effective bifunctional nanohybrid was constructed.•It showed boosting photocatalytic H2 production and MB degradation.•Not only the light absorption but also electron transfer can be effectively enhanced.•The mechanisms were investigated to demonstrate the improved activities.
