Herein, bean sprout-like Co-TiO<sub<2</sub</Ti nanostructures were first synthesized by thermal treatment at 800 °C under Ar-flow conditions using sacrificial ZIF-67 templated on Ti sheets. It was observed that ZIF-67 on Ti sheets started to thermally decompose at around 350 °C and was converted to the cubic phase Co<sub<3</sub<O<sub<4</sub<. The head of the bean sprout structure was observed to be Co<sub<3</sub<O<sub<4</sub<, while the stem showed a crystal structure of rutile TiO<sub<2</sub< grown from the metallic Ti support. Cu sputter-deposited Co-TiO<sub<2</sub</Ti nanostructures were also prepared for photocatalytic and electrocatalytic CO<sub<2</sub< reduction performances, as well as electrochemical oxygen reaction (OER). Gas chromatography results after photocatalytic CO<sub<2</sub< reduction showed that CH<sub<3</sub<OH, CO and CH<sub<4</sub< were produced as major products with the highest MeOH selectivity of 64% and minor C<sub<2</sub< compounds of C<sub<2</sub<H<sub<2</sub<, C<sub<2</sub<H<sub<4</sub< and C<sub<2</sub<H<sub<6</sub<. For electrocatalytic CO<sub<2</sub< reduction, CO, CH<sub<4</sub< and C<sub<2</sub<H<sub<4</sub< were meaningfully detected, but H<sub<2</sub< was dominantly produced. The amounts were observed to be dependent on the Cu deposition amount. Electrochemical OER performances in 0.1 M KOH electrolyte exhibited onset overpotentials of 330–430 mV (vs. RHE) and Tafel slopes of 117–134 mV/dec that were dependent on Cu-loading thickness. The present unique results provide useful information for synthesis of bean sprout-like Co-TiO<sub<2</sub</Ti hybrid nanostructures and their applications to CO<sub<2</sub< reduction and electrochemical water splitting in energy and environmental fields.

Herein, bean sprout-like Co-TiO<sub<2</sub</Ti nanostructures were first synthesized by thermal treatment at 800 °C under Ar-flow conditions using sacrificial ZIF-67 templated on Ti sheets. It was observed that ZIF-67 on Ti sheets started to thermally decompose at around 350 °C and was converted to the cubic phase Co<sub<3</sub<O<sub<4</sub<. The head of the bean sprout structure was observed to be Co<sub<3</sub<O<sub<4</sub<, while the stem showed a crystal structure of rutile TiO<sub<2</sub< grown from the metallic Ti support. Cu sputter-deposited Co-TiO<sub<2</sub</Ti nanostructures were also prepared for photocatalytic and electrocatalytic CO<sub<2</sub< reduction performances, as well as electrochemical oxygen reaction (OER). Gas chromatography results after photocatalytic CO<sub<2</sub< reduction showed that CH<sub<3</sub<OH, CO and CH<sub<4</sub< were produced as major products with the highest MeOH selectivity of 64% and minor C<sub<2</sub< compounds of C<sub<2</sub<H<sub<2</sub<, C<sub<2</sub<H<sub<4</sub< and C<sub<2</sub<H<sub<6</sub<. For electrocatalytic CO<sub<2</sub< reduction, CO, CH<sub<4</sub< and C<sub<2</sub<H<sub<4</sub< were meaningfully detected, but H<sub<2</sub< was dominantly produced. The amounts were observed to be dependent on the Cu deposition amount.

abstract	ZIF-derivatized catalysts have shown high potential in catalysis. Herein, bean sprout-like Co-TiO<sub<2</sub</Ti nanostructures were first synthesized by thermal treatment at 800 °C under Ar-flow conditions using sacrificial ZIF-67 templated on Ti sheets. It was observed that ZIF-67 on Ti sheets started to thermally decompose at around 350 °C and was converted to the cubic phase Co<sub<3</sub<O<sub<4</sub<. The head of the bean sprout structure was observed to be Co<sub<3</sub<O<sub<4</sub<, while the stem showed a crystal structure of rutile TiO<sub<2</sub< grown from the metallic Ti support. Cu sputter-deposited Co-TiO<sub<2</sub</Ti nanostructures were also prepared for photocatalytic and electrocatalytic CO<sub<2</sub< reduction performances, as well as electrochemical oxygen reaction (OER). Gas chromatography results after photocatalytic CO<sub<2</sub< reduction showed that CH<sub<3</sub<OH, CO and CH<sub<4</sub< were produced as major products with the highest MeOH selectivity of 64% and minor C<sub<2</sub< compounds of C<sub<2</sub<H<sub<2</sub<, C<sub<2</sub<H<sub<4</sub< and C<sub<2</sub<H<sub<6</sub<. For electrocatalytic CO<sub<2</sub< reduction, CO, CH<sub<4</sub< and C<sub<2</sub<H<sub<4</sub< were meaningfully detected, but H<sub<2</sub< was dominantly produced. The amounts were observed to be dependent on the Cu deposition amount. Electrochemical OER performances in 0.1 M KOH electrolyte exhibited onset overpotentials of 330–430 mV (vs. RHE) and Tafel slopes of 117–134 mV/dec that were dependent on Cu-loading thickness. The present unique results provide useful information for synthesis of bean sprout-like Co-TiO<sub<2</sub</Ti hybrid nanostructures and their applications to CO<sub<2</sub< reduction and electrochemical water splitting in energy and environmental fields.
