Two step synthesis of TiO2–Co3O4 composite for efficient oxygen evolution reaction

Co3O4@chitosan/La2O3 nanocomposites as innovative, powerful, and recyclable nanocatalysts for sonochemical treatment of benzyl alcohols to obtain the corresponding benzaldehyde derivatives

“…The network parameters agreed well with those of the JCPDS card number 01-078-1969 (standard cubic Co 3 O 4 ). 32 The broad diffraction peaks of CS show 2 θ = 10.60 and 19.9° and it was a good match with the results given in past reports. 6,33 Also, the La 2 O 3 NPs had peaks that are shown at 27.2912°, 28.3643°, 39.6213°, and 46.4585° and are related to La 2 O 3 , which correspond to (222), (300), (400), and (622), respectively, (La 2 O 3 , JCPDS card no.…”

A stable and robust electrode using Copious metal oxide composite for green hydrogen production

“…As best of our knowledge the reported Tafel slope was found to be least for the synthesized Co 3 O 4 @ TiO 2 as compared to the reported Co 3 O 4 and TiO 2 based OER electrocatalyst till date. [38][39][40][41] It is reported that for the reference electrode RuO 2 for OER, the over potential values were decreases for OER with the extent of RuO 2 electrode. At the extreme oxidized condition of RuO 2 with (110) plane, the over potential for OER reported to be 1.96 V vs SHE with Tafel slope of 1.81 mV/dec.…”

“…Co 3 O 4 /TiO 2 composite catalyst synthesized by using wet chemical method, showed OER activity and high durability. [39] Various templating methods were explored to increase the activity of OER reactions.…”

The fast nucleation/growth of Co3O4nanowires on cotton silk: the facile development of a potentiometric uric acid biosensor

“…40 Also, Co 3 O 4 exhibits significant stability and selectivity, which are desirable and have been intensively studied for sensing applications. 47 For improving the performance of Co 3 O 4 , various composite systems have been developed and used for a wide range of sensing applications. 48–58 Most of these composite systems involve multistep synthesis and possess complex structures.…”
