A method for preparing a multi-component alloy catalyst on which a catalytic metal is supported includes preparing a carbon composite having a carbon support coated with a cationic polymer, supporting a catalytic metal containing at least two metal elements on the carbon composite to prepare an alloy catalyst precursor, and washing the alloy catalyst precursor to remove the cationic polymer.

A radiant heater adapted to fit on the head of a hookah. The heater uses one or more resistance wire coils to generate heat which is transferred to shisha in the hookah. The heater includes an exterior chimney which surrounds the resistance ribbon and allows air to flow past the heating elements, and an interior chimney allowing cool air to mix with the heated air. The heated air further mixes with cool air drawn through a ventilation gap below the chimney and the mixed air drawn through one or more vents in a heat shield. The heat shield and hot air vaporize the shisha.

The present disclosure provides a thermal spray alloy system that is more resistant to corrosion than conventional alloy compositions. The disclosed alloy comprises copper as the main component and also potentially nickel, tin, boron, and/or carbon as other principle elements. The alloy composition may utilize a cored wire, and an outer sheath of the cored wire may comprise unalloyed copper. The alloy has superior corrosion resistance to a wide number of corrosive materials, such as hydrogen sulfide, carbon dioxide/carbonic acid, sodium chloride/potassium chloride (salts), bio-fouling, and micro-biologicals. The alloy demonstrates superior thermal conductivity compared to nickel based alloys and stainless steels. The alloy may form an anti-corrosive coating that may be applied to any number of substrates. The disclosed alloy may be applied to a substrate in thick layers, such as between 0.100 inches and 3.0 inches, and may be used to form shapes, such as centralizers.
