a Photothermal effect in photo-involved catalytic reactions. ΔT is the photo-induced temperature increase at catalyst interface and Δ λ is the wavelength shift of cladding mode resonance. b Optical fiber sensing principle and system for operando monitoring light-to-heat at liquid-solid catalyst interface
