Anchoring nickel nanoparticles on three-dimensionally macro-/mesoporous titanium dioxide with a carbon layer from polydopamine using polymethylmethacrylate microspheres as sacrificial templates

Herein, three dimensional (3D) macro-/mesoporous TiO₂@C–Ni composites have been successfully fabricated, which endowed the composites with enhanced performance in catalysis and protein adsorption.
