| الوصف: | Production of alkane fuels from fatty acids by photocatalytic decarboxylation is presently challenging due to low product output efficiency. Here, we report a high-efficiency photocatalytic decarboxylation route, achieving the transformation of high-concentration bioderived long-chain fatty acids to C1-shortened n -alkanes only by using the in situ heat from the photothermal conversion of Fe 3 O 4 . Through the use of high-boiling-point n -alkane solvents for getting the maximum reaction temperature, the single output concentration of C n –1 n -alkane was upgraded from a traditional far less than mmol/L level to the unprecedented mol/L level. We suggest that the heat enhances the strain of aimed C–COO – bond by forcing the standing C-chain down at room temperature onto the Fe 3 O 4 surface, leading photoinduced hole–electron pair easily to be close to and react with the energy-storing C–COO – bond. Meanwhile, the photogenerated electron consumption can shift from conventional PCET of the photo-Koble reaction into a stepwise pathway to form a more favorable carbanion (R – ) intermediate that reacting with H + into RH is highly accelerated with lifting the temperature. Our findings open a new way to upgrade the output efficiency of photocatalytic decarboxylation reaction by reusing the vast majority of incident light energy in a heat form. |
