Second batch of proposed catalysts. Variables represent the following: A; element, B; support, C; temperature (°C), D; CH4 flow (mL min−1), E; O2 flow (mL min−1), F; Ar flow (mL min−1), G; CH4/O2 ratio (mol mol−1), H; C2 yield(%). Note that experimental C2 yields are in reference to C2 yields produced when the catalysts are tested via high-throughput experiments.
