The　low　utilization　of　photogenerated　carriers　and　the　limited　diffusion　of　solvents　are　the　major　bottlenecks　of　Cu2O-based　photocatalysts　for　organic　pollutant　removal.　In　the　effort　to　overcome　these　issues,　this　work,　based　on　the　DFT　calculations　and　inspired　by　the　dandelion　structure,　successfully　synthesized　nanostructured　Cu/Cu2O　photocatalysts　with　effective　solvent　diffusion　channels　and　high　carrier　utilization.　These　catalysts　with　interconnected　nanotube　structure　(the　＂stem＂)　and　hollow　nanosphere　morphology　containing　active　facets　(the　＂fruit＂)　not　only　show　increased　reaction　sites,　but　also　contain　the　Cu/Cu2O　heterojunction　for　facilitating　the　transfer　and　separation　of　photogenerated　carriers　at　the　interface.　Consequently,　the　as-prepared　Cu/Cu2O-4　nanocatalyst　delivers　excellent　photocatalytic　performance,　that　is,　the　removal　efficiency　of　high-concentration　Orange　II　(100　mg　L-1)　reaches　90%　within　10　min　and　can　be　maintained　at　90.4%　after　four　cycles.　This　work　provides　a　promising　route　for　the　construction　of　high-performance　catalysts,　as　well　as　the　mechanism　for　study　of　organic　pollutant　removal.
