"direct catalyst" is correct and can be used in written English.
You could use it to refer to an event or entity that initiates a change in an individual or group. For example, "The news of her promotion was a direct catalyst for change in her attitude and behavior."
"Rarely was silent film — a direct catalyst for the wordless block — ever as resolutely mute as the woodcut novel; intertitles and musical accompaniment helped transmit its meanings," he writes.
His early work in the field, however, has been credited as a direct catalyst for all subsequent efforts to detect the waves, including the creation of a $300 million observatory.
Evidence for the easy dissociation of CH4 is corroborated by direct catalyst activation in the absence of H2.
Full soot combustion by direct catalyst soot contact is not needed in a system as soot combustion by NO2 and O2 gases plays major roles.
R&D projects and the new knowledge that was advanced incrementally in interaction between the company, the environmental authorities and research institutions provided a direct catalyst to the regulatory process.
Three different soot combustion mechanisms are used: (1) passive soot regeneration by NO2, (2) combustion by direct catalyst soot contact, and (3) active soot regeneration with O2 at around 600 °C.
The term 'platform' is used here to underscore that the role of N-polymers is not only to serve as direct catalysts (through loaded metals) but also as co-catalysts/promoters and stabilizing agents.
We have successfully demonstrated a direct, catalyst-free synthesis method of depositing conformal nanocrystalline ZnO films on crystalline and amorphous substrates using a fast thermal plasma CVD process that is preceded by inductive heating.
A very useful and general method to achieve catalytic C H activation is cyclometalation, which employs the aid of a nearby coordinating group to direct the catalyst selectively to one specific C H bond to be activated and functionalized.
"The dialog between the artists and the scientists has been lively, has been exciting," said MIT Professor of Theater Arts Alan Brody, who directs the Catalyst Collaborative with Janet Sonenberg, professor of theater arts and section head of music and theater arts, and URT Artistic Director Debra Wise.
This study focuses on seeking and designing novel NOx direct decomposition catalysts having high activities through theoretical studies using computational chemistry and experimental studies using surface-science techniques.
