Photothermal catalysis represents a clean, efficient, and sustainable approach to harnessing solar energy to drive chemical reactions. However, the inherent trade-off between mass and heat transport efficiencies poses significant challenges to its applicability. Herein, a nature-inspired hollow silica nanocone array catalyst (HSNCA/Co) is developed to address this limitation by enhancing the heat management and sunlight-absorptive ability, while maintaining the exposure of active sites. The nanocone array structure creates dual-flow-rate regions that enable the multidimensional optimization of thermal management and simultaneous mitigation of all three primary heat dissipation pathways. Moreover, the dense silica array enhances light trapping and plasmon coupling efficacy, achieving nearly 99% broadband absorption. In a CO
