This invention provides a tabletop alcohol fireplace, comprising a combustion chamber, a fueling device, and a fireplace body. The combustion chamber is connected to the fueling device. The fueling device includes a fuel inlet unit and a fueling pipe unit. One end of the fueling pipe unit is connected to the fuel inlet unit, and the other end is connected to the combustion chamber. A first recessed area is provided in the middle of the fireplace body. The first recessed area is used to house the combustion chamber. The fueling pipe unit forms an inverted U-shape after passing through a second recessed area in the fireplace body. A protective unit is also provided on the surface of the fireplace body. By providing a fuel inlet unit in the alcohol fireplace, alcohol fuel can be added through this fuel inlet unit. The alcohol fuel then reaches the combustion chamber after passing through the fueling pipe unit, avoiding the accident risk of adding alcohol fuel directly from the combustion chamber; at the same time, the addition of the protective unit further mitigates the risk of use.

The application provides a preparation method of a palladium-tin-gallium ternary alloy nanomaterial, which comprises the following steps: A) under the protection of inert gas, mixing a metal palladium precursor, a metal tin precursor, a metal gallium precursor, methylamine hydrochloride, tri-octyl phosphine and oleylamine, and performing a warming reaction to obtain a preliminary reaction solution; and B) further performing a warming reaction on the reaction solution, washing and drying the reaction solution to obtain the palladium-tin-gallium ternary alloy nanomaterial. The preparation method is simple in operation and controllable in reaction conditions, and the obtained nanomaterial is spherical in shape, uniform in size and good in dispersity. The component of the nanomaterial can be accurately controlled by adjusting the feeding ratio of the metal precursors.
