    摘要: A method of replacing or exchanging non-metal charge balancing cations located at ion-exchanges sites within SAPO frameworks with cations of a transition metal using a solid state ion-exchange process. Transition metal-containing particles are formed on surfaces of SAPO particles, and thereafter the particles are heated in air to initiate the solid-state ion-exchange process. The transition metal-containing particles and the SAPO particles are heated to a temperature and for an amount of time to produce transition metal cations, and for the transition metal cations to replace at least a portion of the non-metal cations located within the SAPO frameworks.

    摘要: The present invention provides a method and apparatus for establishing a chat group. The method performed by a server includes: obtaining an identifier of a user of a first client terminal, an identifier of a chat group to be established and a geographic position of the first terminal; beginning to establish a chat group; selecting at least one second client terminal from a predetermined geographic scope; and inviting a user of the at least one second client terminal to the chat group; receiving authentication information input by the user of the second client terminal from the second client terminal; determining whether the authentication information is correct; if the authentication information is correct, adding the user of the second client terminal into the chat group; and sending information of the second user to the first client terminal; finishing establishing the chat group when a preset finish condition is met.
