What is sintering in the context of ammonia catalysts?
Sintering, in the context of ammonia catalysts, describes the amalgamation of catalyst particles, causing a consequential decline in both surface area and catalytic activity. This intricate phenomenon manifests as the fusion of these particles, compromising the efficiency of the catalyst by diminishing the number of available active sites pivotal for driving the ammonia synthesis reaction. This diminution in surface area and catalytic potency poses a notable challenge, underscoring the importance of mitigating sintering effects to sustain optimal catalyst performance and enhance the overall efficacy of ammonia synthesis processes.
