Embodiment 1

[0028] Disperse 0.5mmol of acetylacetone and 0.07mmol of molybdenum hexacarbonyl in 50ml of N,N-dimethylformamide solution respectively. After ultrasonic dissolution, 5ml of each was mixed evenly and then transferred to a 50ml autoclave. Tighten the lid of the hydrothermal kettle tightly, and place it in an oven at a constant temperature of 60°C for 3 hours. After the reaction was completed, it was naturally cooled to room temperature, and a mixture of ethanol and acetone was added to centrifuge and wash to obtain a palladium tetrahedral nanoframe (Pd TF).

Embodiment 2

[0030] Disperse 0.5mmol of acetylacetone and 0.07mmol of tungsten hexacarbonyl in 50ml of N,N-dimethylformamide solution respectively. After ultrasonic dissolution, take 5ml of each and mix well before transferring to a 50ml autoclave. Tighten the lid of the hydrothermal kettle tightly, and place it in an oven at a constant temperature of 60°C for 3 hours. After the reaction was completed, it was naturally cooled to room temperature, and a mixture of ethanol and acetone was added to centrifuge and wash to obtain a palladium tetrahedral nanoframe (Pd TF).

Abstract

The invention discloses a preparation method of a nano-palladium catalyst and an application of the nano-palladium catalyst in small molecule oxidation. The catalyst is a palladium tetrahedron nano-frame (Pd TF) with an exposed specific crystal face {111}. The nano-frame is prepared by dissolving a palladium precursor and a carbonyl compound in an N,N-dimethylformamide solution and carrying out a hydrothermal reaction. According to the method, surfactants (PVP, CTAB, OAm and the like) used in a traditional nanomaterial preparation method are abandoned, and the palladium catalyst in a specific shape is obtained in a highly controllable mode under the condition that no other ligands exist by means of the reducing performance of the carbonyl compound and the adsorption performance of the carbonyl compound to a specific crystal face. The nanomaterial prepared according to the method is regular in morphology, uniform in size and clean in surface, and shows excellent catalytic activity and stability in micromolecule oxidation. Meanwhile, the preparation method disclosed by the invention is simple in synthesis process, strong in operability, easy in condition control and wide in applicability, and has industrial application potential.

Description

【Technical field】 [0001] The invention belongs to the technical field of catalysts, and in particular relates to a method for preparing a nano-palladium catalyst and its application in small molecule oxidation. 【Background technique】 [0002] With the development of nanomaterials and the maturity of energy conversion technology, alcohol fuel cells show great prospects for sustainable energy supply in the field of portable electronic devices and electric vehicles. Compared with methanol, ethanol has higher energy density and lower Nafion membrane penetration rate as a battery fuel. At the same time, the higher boiling point and non-toxic properties make direct ethanol fuel cells safer in terms of performance. Noble metal nano-palladium is an effective electrocatalyst for ethanol fuel cells, with low toxicity and excellent ethanol catalytic activity, which has attracted extensive attention from all over the world in recent years. [0003] Studies have shown that the catalyti...
